Reference has invalid format: check maybe a bit to harsh?

Hi,

i am using the next branch for testing and i noticed the following: about any git command i execute in a certain repo dies with fatal: Reference has invalid format: 'refs/patches/obd_development/blah:_various_improvements_remote_debugging'

This is probably caused by dce4bab6567de7c458b334e029e3dedcab5f2648 add_ref(): verify that the refname is formatted correctly

The invalid refs(about 30, loose and packed) containing a ':' were created by stgit a long time ago(Dec 2006)

Personally i do not care too much, i patched my git to not die at this point but to only display a error. -> The invalid refs are not accessible, but the rest of the repo still works.

But i'm just wondering if dieing when seeing a single invalid ref might be a bit too harsh since no git tools can be used anymore on this repo at all.

Small side note: It seems t1402-check-ref-format.sh contains not test for the invalid ref char ':' yet. (i do not know if it is tested somewhere else...)

Thanks, Greetings Peter
