[crossfire] [ 1876788 ] Doubled characters in GTK clients (trunk GTK-V2 fixed)

[Kevin R. Bulgrien]

The trunk GTK-V2 client is considered fixed as of SVN 10827.  This
client is compatible with branch servers (metalforge).

Some additional attempt will be made to verify/reproduce/fix problem
in the GTK-V1 client.  Branch client code is quite different from trunk,
but it should be quite simple to backport changes there as needed.

The issue is not closed yet because the trunk GTK-V1 client and both
branch clients have not been examined or worked on yet.

P.S. Credit is due mwedel for facilitating this fix.
