I had a look at the docs; seems to me "standard" is used consistently,
so it makes sense to change to that. Docstring of defcustom:
STANDARD is an expression specifying the variable’s standard
value. It should not be quoted. It is evaluated once by
‘defcustom’, and the value is assigned to SYMBOL if the variable
is unbound. The expression itself is also stored, so that
Customize can re-evaluate it later to get the standard value.
DOC is the variable documentation.
Elisp manual description of defcustom:
The argument STANDARD is an expression that specifies the standard
value for OPTION. ...
The expression STANDARD can be evaluated at various other times,
too—whenever the customization facility needs to know OPTION’s
standard value. So be sure to use an expression which is harmless
to evaluate at any time.
