Just a note: this seems to work on Linux but not on cygwin. It could be that
cygwin's handling of /dev/null is not really compatible with Linux/POSIX.
Or maybe some problem with its patch.
Note that Voldymyr's proposed solution also fails on cygwin. As with
Gustavo's proposal, patch just says "can't file file to patch..." when it sees
either /dev/null or a nonexistent file name.
Cygwin's patch version is 2.5.8, whereas my Linux boxes seem to have 2.5.4.
Not sure if this is relevant or not.
