[PATCH 0 of 1] Allow root or repositories in hgweb.config

[Daniel Santa Cruz]

Currently hgweb.config and in turn hgweb.hgwebdir require one to
specify every repository one wants to allow web acess to.  This patch
allows one to specify a root path that contains repositories inside.

Sample usage (add in hgweb.config:

[rootpaths]
dave = /home/dave/mercurial-repos
byteshack = /home/byteshack/mercurial-repos

[paths]
main = /path/to/some/repo
