	GNU grep has `--include', so I often use something like the
	following:

$ grep -rF --include='*.[ch]' G_foo lib/ raster/ 

$ grep -rF --include=\*.html  g.bar ./ 

	Unfortunately, there's no way to skip directories matching a
	wildcard (e. g.: --exclude=.svn), at least as of GNU grep 2.5.1.

	The `-l' option could be useful as well, e. g.:

$ less $(grep -rlF --include='*.[ch]' G_foo raster/)
