[Freeciv-Dev] (PR#3028) uninitialized value in map/continent code

["Jason Short via RT" <rt@xxxxxxxxxxxxxx>]

When I run the *client* under valgrind, I get this warning about 4 times:

==12809== Conditional jump or move depends on uninitialised value(s)
==12809==    at 0x80C717C: update_continents (map.c:1356)
==12809==    by 0x8077903: handle_tile_info (packhand.c:1615)
==12809==    by 0x8066AC5: handle_packet_input (civclient.c:283)
==12809==    by 0x806A59C: input_from_server (clinet.c:329)

at first glance this looks impossible.  Yet I presume it means that
map_get_continent is returning an "ininitialized" value, meaning the
player continent information is not being fully initialized.

This warning occurred near the start of the game, I don't remember
exactly when (but it was *after* the nation selection had completed).
