Only one file belonging to fish-shell had DOS/bogus line endings,
with `git add' picking up changes after updating .gitattributes:
hostname.fish.
Unsurprisingly, it has code to support cygwin and was likely
worked on by a user on a Windows machine. This will help
such cases in the future.
Also, in pcre2-10.21/, there was RunTest.bat which was (correctly)
CRLF formatted. We don't use this batch script at all, so rather
than LF it or add an exception, blast it away like the other pcre2
files omitted from the repo.
I break compatibility with Mac OS X again, that I don't have access
to. Result: Stuff break, and I have to fix it, so it will perhaps
work. At least, I hope it will work.
Yes, hostname is broken under Cygwin, but for fish it's an issue, as it
makes fish_config more buggy than it needs to be (by making UTF-8 errors
according to Python).
