+    pathnames). Its format may either indicate a path to a single file, or to
+    multiple files with the use of shell-style wildcards (`*` or `?`).
     To avoid surprising behavior when matching targets with <a>PATHPATTERN</a>,
-    it is RECOMMENDED that <a>PATHPATTERN</a> uses the forward slash (/) as
-    directory separator and does not start with a directory separator, akin to

+    it is RECOMMENDED that <a>PATHPATTERN</a> uses the forward slash (`/`) as
+    directory separator and does not start with a directory separator, as is
+    also recommended for <a>TARGETPATH</a>. A path separator in a path SHOULD
+    NOT be matched by a wildcard in the <a>PATHPATTERN</a>.
+
+    Some example <a>PATHPATTERN</a>s and expected matches:
+    * a <a>PATHPATTERN</a> of `"targets/*.tgz"` would match file paths
+      `"targets/foo.tgz"` and `"targets/bar.tgz"`, but not `"targets/foo.txt"`.
+    * a <a>PATHPATTERN</a> of `"foo-version-?.tgz"` matches
+      `"foo-version-2.tgz"` and `"foo-version-a.tgz"`, but not
+      `"foo-version-alpha.tgz"`.
