# Regression test for an off-by-one error:

# Date: Sun, 26 Aug 2007 13:50:45 +0200
# From: Jim Meyering <jim@meyering.net>
#
# The problem arises when the input is a context diff and the second
# byte on a line of context is not a space or tab.
# Patch then happily gobbles/ignores that bogus byte and outputs
# the rest of the line with an additional (NUL) byte at the end.
