Yes, you're right. You don't want to put the names on the stack as it
stands now because then you'll have to "remeber" where you were. So it
puts the current state of the buffer.
I'm always willing to test. But I think it'd be better to put the
*directory* and not the filename into the new stack. It's easy enough to
test if the include filename is relative and adjust the current directory
accordingly. The less directory-path munging we have to do, the better.
(Easier to read, faster and less bug-prone, IMHO.)
So if you write up something you think will work, I'll test it tonight. If
not, I'll try this approach as well.
