I said "it might be harmless".  In private code I would never do such a
thing.  And ‘save-window-excursion’ can't be used here anyway: We would
have to save the configuration current before displaying the mail buffer
and restore it after the mail was sent.  Now suppose the reporter asked
for other completions while editing the mail.  It's the last of those
completions that would be shown after the configuration has been
restored and not the one shown at the time of saving the configuration.

Such a user must first have to be smart enough to write a bug report
with an open *Completions* window.  Any such user will know what to look
for.

I have no better solution.
