This supersedes the patch in 18492.30425.377545.700503(a)parhasard.net, taking
on board Reiner’s input. Tested with XEmacs 21.5; the other
incompatibilities there are independent of this.
lisp/ChangeLog addition:
2008-05-22 Aidan Kehoe <kehoea(a)parhasard.net>
* gnus-util.el (gnus-put-display-table): New.
(gnus-get-display-table): New.
Macros that expand to an `aset' call under GNU, and to a runtime choice
under XEmacs.
* gnus-sum.el (gnus-summary-set-display-table):
Use `gnus-put-display-table', `gnus-get-display-table',
`gnus-set-display-table' for the display table, instead of `aset';
* gnus-xmas.el (gnus-xmas-summary-set-display-table):
Use `gnus-put-display-table', `gnus-get-display-table',
`gnus-set-display-table' for the display table.
