[PATCH] gitweb: Document that gitweb deals with bare repositories

[Jakub Narebski <jnareb@gmail.com>]

Add reminders to gitweb/README and gitweb/INSTALL that gitweb works
with bare repositories.  While it might be obvious to us, it is not
apparently as evident for newcomers.

Does this explanation help?

+- Gitweb deals with bare repositories, which means that gitweb scans for
+  (in the case where $projects_list is a directory to search for
+  repositories) or has to be provided with list of (in the case where
+  $projects_list is a text file) bare repositories, i.e. $GIT_DIR for
+  each repository. The consequence of that is the fact that if you use
+  gitweb to view non-bare repository named 'repo' then gitweb would show
+  (or would have to be provided with) 'repo/.git'.
+
+  If you want to view a buch of non-bare repositories in gitweb but want
+  them named 'repo.git' as is the standard for bare repositories, you
+  can as a workaround populare $projectroot / $project_list with
+  symbolic links to $GIT_DIR of each project you want to publish (have
+  shown) in gitweb.

 - By default all git repositories under projectroot are visible and
   available to gitweb. The list of projects is generated by default by
