# This is an interdiff(1) testcase.
# Test: Prevent patch from checking EOF when not necessary
#
# I think the reason that this fails is that patch(1) assumes that
# fewer post-context lines than pre-context lines indicates end of
# file after the post-context.
#
# Possible work-around: get interdiff(1) to trim the pre-context lines
# so that there aren't more than the post-context lines.
#
# IF YOU GET AN UNEXPECTED PASS (XPASS) when running this test you are
# probably using a version of patch(1) that is missing a fix for
# flushing stderr before exiting.
