Hmm. I was under the impression that xemacs had a different license.
However, the current xemacs is GPL'd.
If there are no non-GPLed implementations of the interfaces used by the
code, then, yeah, that's an issue. [I seem to remember something about
tcl and elisp converging -- there might be an alternative license there.
Then again, maybe not..]
However, even if there are no non-GPLed implementations of the interfaces,
a trivial call to buffer-substring would not be worth worrying about.
If the code in question falls under fair use, copyright isn't an issue:
you need something substantial enough to be considered a copyrightable
work before copyright becomes an issue.
