Usage: diffpp ORIGINAL_FILE < DIFF
Program reads a diff file from its standard input and annotates
ORIGINAL_FILE to show the changes made to the file. The easiest way to use
this program is to use it as an input filter for GNU enscript:
$ enscript -G2re --filter='rcsdiff %s | diffpp %s' *.c *.h
$ enscript -G2re --filter='diff %s~ %s | diffpp %s' *.c *.h
