gitweb: Allow for multivalued parameters passed to href subroutine

jnareb · gitster · commit f22cca44ba50 · 2007-07-28T18:54:56.000-07:00
Make it possible to generate URLs with multivalued parameters in the
href() subroutine, via passing reference to array of values.

Example:
  href(action=&gt;"log", extra_options=&gt;["--no-merges", "--first-parent"])
