Question about git _latest_revision

Question regarding the _latest_revision method in bb.fetch2.git: why do we do an unfiltered 'git ls-remote' and then filter the output on the client side? Wouldn't it be more efficient to just call 'git ls-remote <rev>' with the rev(s) that we actually care about?

Thanks,
Chris

I had vague memories about a good reason:

http://git.yoctoproject.org/cgit.cgi/poky/commit/bitbake/lib/bb/fetch2/git.py?id=83a30dfd495f0b8e90b7b5725c946c659ecbd93d

so it was a sorting problem between proper and lightweight tags.

Cheers,
