This nugget finally gives readers an idea of the sort of issue this
patch wants to "fix", which happens to be related to HFS+ being
case-insensitive. As noted upstream, though, files which are already
tracked, such as ppc/sha1ppc.S, are not subject to .gitignore, so
Dscho's proposed modification to .gitignore:


doesn't actually help. Moreover, this .gitignore change doesn't at all
help the case you describe about new assembly files not being noticed
by "git status" or "git add -A" since any new files won't be named

As Junio said upstream, .gitignore ignoring "*.s" files is the right
thing to do for this project and, as adding new .S files is so rare,
it seems unlikely that a patch changing .gitignore to accommodate the
above use-case for case-insensitive filesystems would make sense to
the project as a whole.
