But since 'diff' output can be fed to a shell or to another program,
it should be quoted for those other programs to be able to process it
correctly.  I don't see how can these two contradicting requirements
be reconciled.

There was never such an implementation of popen on any non-Posix
platform (nor can there be, at least on Windows, because of the need
to support native file names with backslashes).  So such a requirement
is a pipe dream.
