+Subject: [PATCH] filter-repo: fix --replace-text for python3.14
+
+Our handling of globs for --replace-text makes use of fnmatch.translate
+from the python standard library.  Unfortunately, fnmatch.translate
+doesn't just give a regex that can match the given glob somewhere, it
+gives a regex that will only match if the string it is comparing to is
+exactly that glob.  We need a substring search, though, so we have to
+use an ugly hack to butcher the returned regex from fnmatch to get it
+to be what we want.  (It would be nice if python's fnmatch.translate()
+took options for what was wanted, but it doesn't.)  This is fine, except
+that...
+
+python3.14 added '\z' as a synonym for '\Z' in regexes.  No special
+reason, they just wanted there to be more than one way to do it.
+
+Naturally, fnmatch.translate() uses '\z' instead of '\Z', so our regex
+hackery in glob_to_regex() wasn't looking for the right stuff to hack
+off, causing the globs to fail to match text as expected.
+
+Add a python >= 3.14 hack to the existing python variation hacks in
+glob_to_regex() so we can handle this case too.
+
+While at it, the --replace-text test in t9394 did replacements on a
+literal, a glob, and a regex, but it only verified that the glob and
+regex replacements worked.  Supplement it with a check that the
+literal replacement worked too.
