Thanks, I will clean up the braces and commit message. I have to disagree with the 's/reference/dissociate/' comments. It appears this section of option descriptions mostly copies from the descriptions given by 'git clone -h', which outputs: --reference <repo> reference repository --reference-if-able <repo> reference repository --dissociate use --reference only while cloning It is perhaps not the best description, but it means to say when --dissociate is used --reference is only in play for reducing network transfer, not keeping alternates. Those expansions *are* certainly off-putting, they make a long line even more difficult to parse. I just searched that file for ":+" for those types of expressions and I think a patch to fix them would be fairly short. I'll look into making that cleanup patch.
