CVSROOT: /cvs
Module name: src
Changes by: espiecvs.openbsd.org 2006/08/08 04:22:01

Modified files:
        usr.bin/rcs : diff3.c

Log message:
let ed_patch_lines work with a c command that encompasses the last line
of the file. The TAILQ structures specifically contain an extra `first line'
to avoid this kind of issue, but no extra last line.
Instead of walking beyond the end of the structure, and wondering at the
null pointer, keep a pointer before the deleted block, as this one is
guaranteed to exist.

Fix Matthieu's testcase.

okay joris, xsa
