        src/external/bsd/nvi/dist/common: screen.c

Log Message:
screen_end can be called multiple times for the same screen.
Work around segfault in TAILQ_REMOVE by abusing the tqe_prev pointer
as a flag that identifies an already removed node.

This should really be solved by calling screen_end only once or by
keeping state explicitely in the screen structure.
