next-error

[Kevin Rodgers]

I maintain a small package that calls next-error, which in Emacs 21.3
selected the source buffer in accordance with compilation-goto-locus's
doc string:

| Selects a window with point at SOURCE, with another window displaying ERROR.

But a user reports that in CVS Emacs (specifically, the July 9 snapshot
available at www.crasseux.com), next-error selects the *grep*
compilation buffer instead of the source buffer.  Is that true, and is
the change intentional?  If so, what is the right way to get the source
buffer after calling next-error now?

Thanks,
