Re: byte compiling defcustom

[Richard Stallman]

    The patch below implements the desired feature: it byte-compiles the
    default-value-expression (first part of the hunk) as well as any
    keyword arguments (second part of the hunk).  Notice that the second
    part actually simplifies the code.

I don't see any particular benefit in compiling these, but I don't
object to trying this in the trunk.

Can you make sure that very simple default values do not get compiled?
