[PATCH] apply.c: handle incomplete lines correctly.

The parsing code had a bug that failed to recognize an
incomplete line at the end of a fragment, and the fragment
application code had a comparison bug to recognize such.  Fix
them to handle incomplete lines correctly.

Add a test script for patches with various combinations of
complete and incomplete lines to make sure the fix works.
