 v.in.garmin and v.in.mapgen use the 'tac' utility command.  This is not
 included in Mac OS X, and possibly some other *nix flavors.

 It looks like 'tail -r' achieves the same purpose.  Included are patches
 for v.in.garmin and v.in.mapgen.  It tested OK with v.in.mapgen on a
 mapgen file from NOAA.  I have no matlab file to test it on, or garmin
 file.

 Feedback and testing would be helpful.

 Also, the BSD manpage I have for tail says the -r flag is an extension to
 the POSIX spec for tail, so it's possible it's not completely portable.
 Maybe a further test for the flag is needed.
