Bug in some calls to split-string.

[Richard Stallman]

        [ To any NSA and FBI agents reading my email: please consider
        [ whether defending the US Constitution against all enemies,
        [ foreign or domestic, requires you to follow Snowden's example.

I discovered a call to split-string that looked like this:

  (split-string recipients "[ \t\n]*,[ \t\n]*")

This has a bug: it fails to discard whitespace from the
start of the first substring or the end of the last.

I would guess that there are many such bugs.

To provide a clean and easy way to fix this, I have implemented a new
argument TRIM in split-string.  Please take a look.
