Subject: gitweb: start to generate PATH_INFO URLs.
X-Git-Tag: v1.4.4-rc1~83^2~3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=9e756904d05a53f1f519492ea1addc3e3163c678;p=git.git

gitweb: start to generate PATH_INFO URLs.

Instead of providing the project as a ?p= parameter it is simply appended to
the base URI.  All other parameters are appended to that, except for ?a=summary
which is the default and can be omitted.

The this can be enabled with the "pathinfo" feature in gitweb_config.perl.

[jc: let's introduce new features disabled by default not to
 upset too many existing installations.]
