[XEmacs] signal vs. error
There is a lot of changes in customize like this:
- (error "Keyword %s is missing an argument" keyword))
+ (signal 'error (list "Keyword is missing an argument"
keyword)))
Presumably dating back to this:
1997-12-15 Hrvoje Niksic <hniksic(a)srce.hr>
* widget.el (define-widget): Check the arguments.
* cus-edit.el (customize-face): Use `check-argument-type'.
(custom-variable-value-create): Use `signal' to signal error.
(custom-variable-reset-saved): Ditto.
(custom-variable-reset-standard): Ditto.
(custom-face-reset-saved): Ditto.
...
What is the purpose of that change?
