[Users] path expansion in git/darcs/hg repositories

[Eric Seidel]

I think it would be best to add support for a case like this

>> !TARGET   = $ARR
>> !TYPE     = git
>> !URL      = git://someurl/PersonalCode
>> !AUTH_URL = rhaas3 at someotherurl/PersonalCode
>> !REPO_PATH= Cactus/Hydro/$1/experimental/$2
>> !CHECKOUT =
>> Scotch/SoundSpeed

This would really mean treating REPO_PATH like an actual path instead of just a symbol to replace with something else from CHECKOUT. It might not even require modification to the current ET thornlist.

Agreed. It would also not be very user-friendly to rely on hidden directories..

I don't really think this matters, unless there's a situation where someone would need to checkout a single file from an svn repo, since you can easily checkout whichever directories you want using svn, and add more to the thornlist later if necessary. Sorry for the run-on sentence there...
