Hi,

I'm taking a crack at cleaning up the (rather large) set of warnings
from compiling the JDEE Lisp code.

This is a first patch, and it is low hanging fruit: all the
"save-excursion followed by set-buffer" warnings are fixed. That pair is
replaced by with-current-buffer. By my count that fixes 40 warnings.

The current usage became a warning in Emacs 23 in late 2009:
save-excursion does not save you from changes in the buffer you switch
*to* using the following set-buffer. So, really, the only thing you
*should* save before setting the new buffer is the current buffer!

I've been using this patched version for over a week now. It's a simple,
if lengthy, patch and as expected it works out just fine. There should
be no compatibility problems since with-current-buffer has been around
at least 14 years.

Now onto the remaining 176 warnings ;-)

Cheers!
