 From cg-tag in 0.16:

(echo $name | egrep -qv '[^a-zA-Z0-9_.@!:-]') || \
         die "name contains invalid characters"

WHY?  I can see rejecting control characters, but the above will reject 
pretty much anything written in a non-English language, which is rude to 
say the least...

Probably it can safely be updated to use check-ref-format, and I
suspect that the only reason why it does not do so is because
check-ref-format came later.
