Subject: hooks/pre-commit.sh: don't wail on detached head for missing .top* files
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=topgit.git;a=commitdiff_plain;h=c32d1dd4fcafad3f9c570adeda580a90d564a3af;hp=4096b92662b36f45f4770a8c0d987e32e157746c

hooks/pre-commit.sh: don't wail on detached head for missing .top* files

This fixes a warning

	fatal: ref HEAD is not a symbolic ref

when your HEAD is detached.

And branches under refs/top-bases/ don't need these files either.
