r.median invokes r.stats via system(), using a single quote:
strcpy (command, "r.stats -a '");
strcat (command, G_fully_qualified_name (basemap, base_mapset));
strcat (command, ",");
strcat (command, G_fully_qualified_name (covermap, cover_mapset));
strcat (command, "'");
/* strcpy (command,"cat /tmp/t"); */
stats_fd = popen (command, "r");
sprintf (command, "r.reclass i='%s' o='%s'",
G_fully_qualified_name (basemap, base_mapset), outmap);
system() uses the platform's shell: /bin/sh on Unix, cmd.exe on
Windows NT/2K/XP, command.com on 95/98/ME. Single quotes won't work
with the Windows shells.
r.average doesn't quote the map names, and uses double quotes around
the output filename:
sprintf (command, "%s -anC input=%s,%s fs=space > \"%s\"",
STATS, basemap->answer, covermap->answer, tempfile1);
Using double quotes should suffice so long as the map name doesn't
contain $ or ` (a double quote would also be problematic, but isn't
legal in map names).
Ultimately, we need a Windows implementation of G_spawn_ex(), so that
we can avoid the shell altogether.
