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

[Peter Oberndorfer <kumbayo84@arcor.de>]

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
