Re: [AUCTeX-devel] Changes in font locking

Reply-To set to xemacs-beta; no need to bother auctex-devel further with XEmacs internal details.

And I see in an earlier post you've already identified the place where current Emacs diverged, which was done by Stefan Monnier. I'm convinced; we don't need to understand the underlying implementation (I thought we did need to understand copy-syntax-table, at least, but in the first place that call was evidently just a thinko that we sync'ed to), only to test that (let ((copy (copy-syntax-table (syntax-table)))) (or (with-syntax-table (obviously-different-from-current-syntax-table) (test-syntax-table-equal copy (syntax-table))) (not (test-syntax-table-equal copy (syntax-table))))) evaluates to nil, as we expect. (N.B. XEmacs's implementation of syntax tables is sparse, so #'equal need not give the right results. In particular, (make-syntax-table) and (standard-syntax-table) return objects that are equivalent as syntax tables but not #'equal.) (Thinking out loud ....) Regression tests for the bug and that with-syntax-table works as expected should be added. Also review uses in core (probably none) and the packages (probably few or none outside of Gnus and AUCTeX). The use case review can be done "off-line". Is this relevant to 21.4?

so far? Would you be willing to help with some part of the code review and/or test-writing?
