Re: [XEmacs] signal vs. error

There is a lot of changes in customize like this:
- (error "Keyword %s is missing an argument" keyword))

What is the purpose of that change?
Providing actual arguments to errors is a good idea, especially in
low-level code. Code that traps the error can in that case get more
context about the error without the need to parse the error message
string. Most errors in XEmacs C code are signaled that way.
