--- Comment #1 from Igor Kolesnik <igorkolesnik at posteo.net> ---
Looks like it strips out the trailing eol character when calling execute in
prpending().  Inside execute memchr() fails to find eol and returns NULL.

This occurs in 13.0-CURRENT as well.

BSD grep does not contain such bug.

Attached is a proposed patch.
