Here's what I meant:  minor-mode foobar is a copyrighted work
with a license incompatible with the GPL.  It uses a call to
buffer-substring.  The buffer-substring copyright owner could
say:  You can't do that; implement your own buffer-substring.

Of course, it's likely that _any_ minor-mode written for Emacs
has a call to some Emacs internal every second line, and not a
single call to buffer-substring.

Neither am I.  I'm just wondering where the line is.

Years ago when I satrted coding elisp and wasn't concerned about
licensing issues, I thought I was okay as long as I didn't load
anything via 'require'.  But obviously I was using other people's
copyrighted code way before that.
