Fixes bug#29923 'insert-abbrev-table-description' with a non-nil READABLE inserts Lisp forms suitable for evaluation to restore the defined abbrevs. We don't have to insert a form for tables that do not have any abbrevs. To implement this, we need to filter out system abbrevs before checking if a table is empty, because system abbrevs were previously skipped in the 'abbrev--write' call, at which point we would already have started inserting the beginning of a table definition form. * lisp/abbrev.el (insert-abbrev-table-description): Skip inserting empty tables when READABLE is non-nil. Clarify behavior in documentation string. (abbrev--write): Remove system abbrev check. * doc/lispref/abbrevs.texi (Abbrev Tables): Document behavior with empty tables. * etc/NEWS: Mention the change in behavior of 'insert-abbrev-table-description'. |
