Re: [PATCH 1/3] gitweb: Move check-ref-format code into separate function

Stricly speaking pure refactoring (no functional change, e.g. no assign
to $input) would be  "check_ref_format($input) or return undef;", or even
"return check_ref_format($input);" if we keep check_ref_format() passthru
on valid refname.

Exactly.
