 Consider, e. g.:
   bash$ (r=baz ; a=foo ; b=bar ; r.mapcalc "\"$r\" = \"$a\" + \"$b\"")

 Note that r.mapcalc allows map names to be quoted using either single or
 double quotes, so the above can be written as:

   bash$ (r=baz ; a=foo ; b=bar ; r.mapcalc "'$r' = '$a' + '$b'")

 This is probably clearer than using backslash and double-quote.
