That reminds me of another issue: the mapset search path is determined
by the contents of the SEARCH_PATH file in the current directory, not
the environment, so it isn't affected by G__create_alt_env() and
G__switch_env(). Also, the contents are cached, so switching mapset or
location won't change any search path.

That isn't relevant to the MASK, though, as that is always obtained
from the current mapset (G_mapset()), not the mapset search path.
