Hmmm.  Never tried negative numbers.  Didn't know that they were
specified as valid.

Yea.  Perl/sed/awk.  The ~/.xastir/config/map_index.sys file
contains these entries.  You can figure out the column format.

Near as I can tell that's not one of the layers we support.  At
least I only have two of those types of maps on my system, which
means that it's likely a map layer that I didn't support, and when I
enable it, I get X's with numbers too.  Can't remember what that
layer is off-hand.
