Some of the ref manipulation tools (git-for-each-ref and git-show-ref in
particular) would not handle hidden (~ /^\./) refs. This may be an
acceptable or possibly even desirable behaviour for the ref walkers and
repackers, but git-show-ref hiddenrefname must work.

No.

Refnames MUST NOT start with a ".". 

It's not even about the traditional unix "hidden file" thing. It's simply 
a syntactic issue. A ref cannot start with a ".", because we use things 
like ".." and "..." to separate them.

We do not forbid a refname that ends with a ".", but I think it
was a mistake.  We _can_ disambiguate the ones that begin with a
"." by saying "whatever..heads/.I-begin-with-dot", but not the
ones that end with "heads/I-end-with-dot...end-of-range".
