bug#64689: 30.0.50; message-mode bug

[Devon Sean McCullough]

Typing my prior bug report, left-clicking the To:-line
beeps with the error message <tool-bar> <mouse-1> is undefined
and typing this bug report, it now errs on the Subject:-line as well
but not the From:-line nor the first two characters
of the To: and Subject: lines.

         Peace

I cannot reproduce this, but my build is not a PGTK build.  Maybe this
is specific to PGTK?
