-  Here are the values we're masking off to decide what operations to do.
-  Note that since EV_READ|EV_WRITE.
-
-  Note also that this table is a little sparse, since ADD+DEL is
-  nonsensical ("xxx" in the list below.)
-
-  Note also also that we are shifting old_events by only 5 bits, since
-  EV_READ is 2 and EV_WRITE is 4.
-
-  The table was auto-generated with a python script, according to this
-  pseudocode:
-
-      If either the read or the write change is add+del:
-	 This is impossible; Set op==-1, events=0.
-      Else, if either the read or the write change is add:
-	 Set events to 0.
-	 If the read change is add, or
-	    (the read change is not del, and ev_read is in old_events):
-	       Add EPOLLIN to events.
-	 If the write change is add, or
-	    (the write change is not del, and ev_write is in old_events):
-	       Add EPOLLOUT to events.
-
-	 If old_events is set:
-	       Set op to EPOLL_CTL_MOD [*1,*2]
-	Else:
-	       Set op to EPOLL_CTL_ADD [*3]
-
-      Else, if the read or the write change is del:
-	 Set op to EPOLL_CTL_DEL.
-	 If the read change is del:
-	     If the write change is del:
-		 Set events to EPOLLIN|EPOLLOUT
-	     Else if ev_write is in old_events:
-		 Set events to EPOLLOUT
-		Set op to EPOLL_CTL_MOD
-	     Else
-		 Set events to EPOLLIN
-	 Else:
-	     {The write change is del.}
-	    If ev_read is in old_events:
-		 Set events to EPOLLIN
-		Set op to EPOLL_CTL_MOD
-	    Else:
-		Set the events to EPOLLOUT
-
-      Else:
-	   There is no read or write change; set op to 0 and events to 0.
-
-      The logic is a little tricky, since we had no events set on the fd before,
-      we need to set op="ADD" and set events=the events we want to add.	 If we
-      had any events set on the fd before, and we want any events to remain on
-      the fd, we need to say op="MOD" and set events=the events we want to
-      remain.  But if we want to delete the last event, we say op="DEL" and
-      set events=(any non-null pointer).
-
-  [*1] This MOD is only a guess.  MOD might fail with ENOENT if the file was
-       closed and a new file was opened with the same fd.  If so, we'll retry
-       with ADD.
-
-  [*2] We can't replace this with a no-op even if old_events is the same as
-       the new events: if the file was closed and reopened, we need to retry
-       with an ADD.  (We do a MOD in this case since "no change" is more
-       common than "close and reopen", so we'll usually wind up doing 1
-       syscalls instead of 2.)
-
-  [*3] This ADD is only a guess.  There is a fun Linux kernel issue where if
-       you have two fds for the same file (via dup) and you ADD one to an
-       epfd, then close it, then re-create it with the same fd (via dup2 or an
-       unlucky dup), then try to ADD it again, you'll get an EEXIST, since the
-       struct epitem is not actually removed from the struct eventpoll until
-       the file itself is closed.

+  Here are the values we're masking off to decide what operations to do.
+  Note that since EV_READ|EV_WRITE.
+
+  Note also that this table is a little sparse, since ADD+DEL is
+  nonsensical ("xxx" in the list below.)
+
+  Note also also that we are shifting old_events by only 5 bits, since
+  EV_READ is 2 and EV_WRITE is 4.
+
+  The table was auto-generated with a python script, according to this
+  pseudocode:[*0]
+
+      If either the read or the write change is add+del:
+	 This is impossible; Set op==-1, events=0.
+      Else, if either the read or the write change is add:
+	 Set events to 0.
+	 If the read change is add, or
+	    (the read change is not del, and ev_read is in old_events):
+	       Add EPOLLIN to events.
+	 If the write change is add, or
+	    (the write change is not del, and ev_write is in old_events):
+	       Add EPOLLOUT to events.
+
+	 If old_events is set:
+	       Set op to EPOLL_CTL_MOD [*1,*2]
+	Else:
+	       Set op to EPOLL_CTL_ADD [*3]
+
+      Else, if the read or the write change is del:
+	 Set op to EPOLL_CTL_DEL.
+	 If the read change is del:
+	     If the write change is del:
+		 Set events to EPOLLIN|EPOLLOUT
+	     Else if ev_write is in old_events:
+		 Set events to EPOLLOUT
+		Set op to EPOLL_CTL_MOD
+	     Else
+		 Set events to EPOLLIN
+	 Else:
+	     {The write change is del.}
+	    If ev_read is in old_events:
+		 Set events to EPOLLIN
+		Set op to EPOLL_CTL_MOD
+	    Else:
+		Set the events to EPOLLOUT
+
+      Else:
+	   There is no read or write change; set op to 0 and events to 0.
+
+      The logic is a little tricky, since we had no events set on the fd before,
+      we need to set op="ADD" and set events=the events we want to add.	 If we
+      had any events set on the fd before, and we want any events to remain on
+      the fd, we need to say op="MOD" and set events=the events we want to
+      remain.  But if we want to delete the last event, we say op="DEL" and
+      set events=(any non-null pointer).
+
+  [*0] Actually, the Python script has gotten a bit more complicated, to
+       support EPOLLRDHUP.
+
+  [*1] This MOD is only a guess.  MOD might fail with ENOENT if the file was
+       closed and a new file was opened with the same fd.  If so, we'll retry
+       with ADD.
+
+  [*2] We can't replace this with a no-op even if old_events is the same as
+       the new events: if the file was closed and reopened, we need to retry
+       with an ADD.  (We do a MOD in this case since "no change" is more
+       common than "close and reopen", so we'll usually wind up doing 1
+       syscalls instead of 2.)
+
+  [*3] This ADD is only a guess.  There is a fun Linux kernel issue where if
+       you have two fds for the same file (via dup) and you ADD one to an
+       epfd, then close it, then re-create it with the same fd (via dup2 or an
+       unlucky dup), then try to ADD it again, you'll get an EEXIST, since the
+       struct epitem is not actually removed from the struct eventpoll until
+       the file itself is closed.
