 Hi,

  - MS-Windows sets %TMP%
  - MSys translates existing DOS variables into shell variables
  - %TMP% becomes $TMP
  - many shell scripts use {{{ TMP=`g.tempfile -p $$` }}}
  - many shell scripts try to remove $TMP* files even if they don't exist.
  - potential ka-boom if g.tempfile never ran


 I just triggered this with a typo: `m.proj hlep`


 should we `unset TMP` at the start of any script which uses it?

 {{{
 d.polar
 db.dropcol
 i.fusion.brovey
 m.proj
 r.in.wms
 r.mask
 r.plane
 r.regression.line
 r.univar.sh
 v.colors
 v.db.dropcol
 v.db.renamecol
 v.db.univar
 v.in.garmin
 v.in.gpsbabel
 v.in.lines
 v.in.mapgen
 v.in.wfs
 v.out.gpsbabel
 v.rast.stats
 v.univar.sh
 }}}

 or should we do that as part of WinGrass's Init.sh?
