If named boolean option -path_info is passed to href() subroutine, it
would use its value to decide whether to generate path_info URL form.
If this option is not passed, href() queries 'pathinfo' feature to
check whether to generate path_info URL (if generating path_info link
is possible at all).
href(-replay=>1, -path_info=>0) is meant to be used to generate a key
for caching gitweb output; alternate solution would be to use freeze()
from Storable (core module) on %input_params hash (or its reference),
e.g.:
$key = freeze \%input_params;
or other serialization of %input_params.
While at it document extra options/flags to href().

There is no change in the patch with v3, as compared to v2.
Note that in the caching patch by J.H. from "Gitweb caching v5" thread
(and top commit in git://git.kernel.org/pub/scm/git/warthog9/gitweb.git,
gitweb-ml-v5 branch) the key was generated as "$my_url?".$ENV{'QUERY_STRING'}
which wouldn't work with path_info URLs, but on the other hand gitweb
at git.kernel.org doesn't use path_info URLs (perhaps even doesn't
support them).
Using href(replay=>1,full=>1,path_info=>0) has additional advantage
over using $cgi->self_url() in that it also does not depend on
ordering of parameters in handcrafted URLs.
