Actually, the early bailout was sort of intentional. The problem is
the ambiguity: does git.example.com/opml refer to the opml project, or
does it refer to the opml action?

Good point. Though my patch does not break any existing functionality,
it does not fix the case where a project matches the action.

HOWEVER, href() *does* create the opml action as git.example.com/opml,
so gitweb is currently broken in the sense that ti doesn't correctly
parse its own pathinfo output. So the question is: shall we go with
this patch, preventing pathinfo from working for projects named like a
no-project gitweb action, or should we fix href() to not generate
pathinfo unless project is defined?

A variation of the latter approach is to modify href() to use pathinfo
if there is a project or there is no project matching the name of the
action. The only downside to this approach is that a URI that refers to
an action when first generated could resolve to a project in the future,
if a project of the same name were added.

And don't forget the case of a new action being introduced which is
named like an existing project.

I suspect we'd be much better off by not using pathinfo at all for
global actions. Other possible solutions would be to have something
like an ADDITIONAL prefix to the path (like project/projectname vs
action/actionname, so we would have git.example.com/action/opml or
git.example.com/project/example-project) but this is WAY too verbose.

At most, we could add a suffix to global actions to reduce the chance
of name conflict, such as using

git.example.com/opml.xml

or

git.example.com/project_index.txt

but I don't like these solution either: I'd rather have these be
provided as filenames in the response header.

Incoming patch to not make use of path_info without project.
