Handle varalias chains, custom variables in #'user-variable-p.
src/ChangeLog addition:
2008-08-23 Aidan Kehoe <kehoea@parhasard.net>
* eval.c (Fuser_variable_p): Moved to symbols.c
* symbols.c (Fcustom_variable_p): Moved here from custom.el.
(user_variable_alias_check_fun): Mapper function used in
`user-variable-p'.
(Fuser_variable_p): Moved here from eval.c, to allow it to examine
the variable alias chain. Expanded to check each entry in the
variable alias chain for signs of being a user variable;
documentation updated, noting the differences between GNU's
behaviour and ours (ours is a little more sensible)
(map_varalias_chain): New.
Given a C function, call it at least once for each symbol in a
symbol's varalias chain, signalling an error if there's a cycle,
and returning immediately if the function returns something other
than Qzero.
(Fdefvaralias): Correct the use of the word "alias" in the
docstring and in the argument name. Motivate this in a
comment. Add support for a DOCSTRING argument, something GNU has
too, and document this
* gc.c (vars_of_gc): Start the docstring of
`garbage-collection-messages' with an asterisk, to indicate that
it's a user variable.
lisp/ChangeLog addition:
2008-08-23 Aidan Kehoe <kehoea@parhasard.net>
* custom.el: Move #'custom-variable-p to C, since it's now called
from #'user-variable-p.
