Some git web interfaces use different paths for files (blobs) and
directories when it comes to browsing; this means we need to have a
separate field for the base URL for files.
Additionally, Gitweb typically puts the path within the URL instead of
at the end (although the parameters can be reordered) and cannot handle
the file parameter (f=) being specified with no value. So, to add some
flexibility, add the ability to use a positional macro %path% to
optionally specify where to put the path. If needed, square brackets
can be used in conjunction with %path% to exclude parts of the string
when there is no path, i.e. we want to browse the root. For example, the
following base URL:
http://git.example.com/?p=somerepo.git;a=tree;[;f=%path%];hb=HEAD
would be translated to this with a path of "path/to/dir":
http://git.example.com/?p=somerepo.git;a=tree;f=path/to/dir;hb=HEAD
and this if no path were specified:
http://git.example.com/?p=somerepo.git;a=tree;hb=HEAD
