Actually second should be [PATCH/RFC] as it penalizes the "not found"
case (extra check 'if really not found').

First patch, which is modified version of Guillaume Seguin patch solves
problem that links in gitweb does lead to correct 'tag' view, while the
second one solves the problem from the other side: instead of ensuring
that links in gitweb are unambiguous it tries to resolve ambiguity.


The problem is caused by the fact that git _always_ prefer heads (head
refs) to tags (tag refs), even when it is clear
  $ git cat-file tags ambiguous-ref
that we want a tag. So alternate solution would be to correct
git-cat-file.

True, current way of testing gitweb does not allow for test which would
detect breakage noticed by Guillaume.

It would be quite easy I think to add checking if gitweb returns
expected HTTP return code (HTTP status). So what is the portable way
to check if first line of some output matches given regexp (given fixed
string)?
