[GRASS-dev] Error in redrawing text layer in gis.m

[Michael Barton]

I think I found and fixed it.

It was not in grid but in the font setting environmental variable in
dtext.tcl.

The script was resetting GRASS_FONT after running d.text.new. If GRASS_FONT
was not initially set, the script tried to set it to "". This caused a
failure in running d.frame -e for some reason. Anyway, if GRASS_FONT is
initially not set, it is unset (rather than being set to "") after running
d.text. I think this fixes the problem.

Please test and let me know.

Michael
