gimp/plug-ins/common/grid.c
Sven Neumann e26e778d9a app/drawable_cmds.c applied (a modified version of) a patch from Garry R. 
* app/drawable_cmds.c
        * tools/pdbgen/pdb/drawable.pdb: applied (a modified version of) a
        patch from Garry R. Osgood <gosgood@idt.net> that should fix bug #2202
        and problems with the Warp plug-in.

        * app/main.c
        * po-plug-ins/POTFILES.in
        * plug-ins/common/mail.c: applied a patch from
        SHIRASAKI Yasuhiro <yasuhiro@awa.tohoku.ac.jp> that handles i18n issues         and fixes a problem in the mail plug-in.
        ( Could someone please check if the change to app/main.c is the right
          thing to do ?! )

        * po-plug-ins/POTFILES.in
        * plug-ins/common/grid.c
        * plug-ins/gap/iter_ALT/gen/plug_in_grid_iter_ALT.inc:
        checked in a new version of the Grid plug_in developed by
        Tom Rathborne <tomr@aceldama.com> and me.
