Re: `remote-shell-program' should be customizable

[Richard Stallman]

    * Most of this should be done at runtime, not in paths.el, which is
      dumped.  There's no reason that rmail-spool-directory should be the
      same on the target system as the build system, for instance -- it's
      rather random on systems I'm familiar with.

That sounds like a good improvement, if it is done right,
so that any settings made by the user are not overriddem once
relevant packages are read.

Want to send patches?  However, this may as well wait till after the
current release.
