[PATCH] git-svn: remove leading slashes from fetch lines in the generate config

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

 



We were previously sensitive to leading slashes in the fetch
lines and incorrectly writing them to the config if the user
used them (needlessly) in the command-line.

This fixes the issue and allows us to play nicely with legacy
configs that have leading slashes in fetch lines.

Thanks to Bradford Smith for figuring this out for me:
