vim-patch:7.4.819

Problem:    Beeping when running the tests.
Solution:   Fix 41 beeps. (Roland Eggner)

901e58c243

Applied cleanly, except for files test29.in, test4.in, test61.in, test82.in,
test83.in, test90.in, test95.in, which were all converted to lua tests, and
version.c.

Some beeps remain, but this is much better.
