Re: shell-command - missing shell-quote-argument for program?

[Richard Stallman]

    If we quote emerge-command and the various emerge-*-program, we in
    effect disallow them to be shell commands with switches.  Is that
    reasonable?  If it is, then we should quote the programs.

If that's what these variables do, their values should not be quoted,
so that they can include some arguments.

Since that exists only to be sent as arguments,
it should not be quoted.  The user will put in whatever
quoting is called for.
