 GRASS GIS what to run (#2579),

 After r65252 and r65294 (see #2579) you can use (in trunk, upcoming 7.1
 release):

 {{{
 C:\path\to\grass C:\path\to\demomapset --exec g.mkfontcap
 }}}

 This should run `g.mkfontcap` in a regular GRASS session but without
 touching user's GRASS rc file in home directory (if it does, it's a bug),
 so the last used Mapset will be still whatever user or installer sets.

 GRASS is installed, right? So this should work in theory.

 > One other thing is that it is not clear to me what changed that now
 GISRC variable is required but it was not before.

 Let's say that we don't need to deal with this because it is expected that
 GRASS module requires `GISRC` to be set. I'm just not sure why it is
 expected by `​g.mkfontcap` (probably it calls some GRASS library
 functions).
