Subject: r.patch: creating support files fails when 1st map isn't local

When running r.patch with "input=aspect at first_mapset,aspect at second_mapset",
building support files fails with the following errors:

r.patch: percent complete:  100%
CREATING SUPPORT FILES FOR aspect
WARNING: unable to find [aspect] in [(null)]
WARNING: category support for [aspect] in mapset [(null)] missing



grass/src/raster/r.patch/cmd/support.c header:
/*
 * creates new category and color structures from the patching
 * files category and color files
 *
 * the first patch file is used as the basis. Its cats and colr
 * are read into the final cats/colr structures.
 * Then the other patching layers cats/colr are added to the
 * final cats/colr only if these patching layers actually
 * contributed new categories to the final result
 */


thanks,
Hamish
