patch, 5 partsgitweb: improve directory hierarchy handling

There are two main things in this little seris:

The second and third patches improve gitweb's project filter feature, which is for listing just the projects in a subdirectory.

The fourth and fifth allow the admin to use a directory hierarchy to automatically categorize projects in gitweb.

Tony Finch (5):
  gitweb: fix typo in man page
  gitweb: if the PATH_INFO is incomplete, use it as a project_filter
  gitweb: add a link under the search box to clear a project filter
  gitweb: optionally set project category from its pathname
  gitweb: make category headings into links when they are directories
