Re: [PATCH 4/5] gitweb: Add a feature for adding more branch refs

With multi-valued we won't be able to override earlier / more generic

           extrabranchrefs
 # or    extrabranchrefs =
           extrabranchrefs = wip other

resulting in ('wip', 'other').

Please don't, unless you are going to change the entire config
machinery (including config.c bits that are used by the rest of the
system) to follow such a convention to "clear settings so far read".

Hmmm... 'snapshot' feature ignores invalid values, but in this case
formerly valid compression schemes might get invalid via tightening
%known_snapshot_formats, and we don't want existing config getting
suddenly invalid.

Sorry, but what does check-ref-format have to do with "formerly
valid compression scheme that suddenly gets invalidated"???
