hgrc.5: do not mention "name: value" syntax
This was supported in versions prior to 1.3 where we used the standard
Python ConfigParser. The new config parser never supported it.
Basic install:
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
