[PATCH] repo-config: trim white-space before comment

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Earlier, calling

	git-repo-config core.hello

on a .git/config like this:

	[core]
		hello = world ; a comment

would yield "world " (i.e. with a trailing space).

	It actually was a buglet in parse_value(), so it was not only 
	repo-config which was affected.

	Obviously, this patch comes on top of the --get-regexp patch, but
	feel free to apply without that.
