You cannot write a command to change the shell's environment. This is
the main reason why we have $GISRC and G_getenv() etc instead of just
using environment variables.

Although, GISRC shouldn't need to be changed; it should remain
constant for the duration of a session.

And, environment issues aside, you can't make the shell close the
history file and start writing a new one. You just have to accept the
fact that the history will be stored in the starting mapset.
