Sometimes bisect logs have CRLF newlines. (E.g., if they've been edited
on a Windows machine and their LF-only nature wasn't preserved.)
Previously, such log files would cause odd failures deep in the guts of
git bisect, like "?? what are you talking about?" or "couldn't get the
oid of the rev '...?'" (notice the trailing ?) as each line's CR ends up
part of the final value read from the log.

This commit fixes that by stripping CRs from the log before further
processing.

A regression test that fails without the git-bisect.sh change, "bisect
replay with CRLF log" has been added as well.

Were anyone to intentionally be using terms/revs with embedded CRs,
replaying such bisects will no longer work with this change. I suspect
that this is incredibly rare.
