Bug#918536: /etc/reportbug.conf: bad example for mua

[Jakub Wilk <jwilk@jwilk.net>]

Package: reportbug
Version: 7.5.1

/etc/reportbug.conf contains the following example:

  # mua 'mutt -H'

But this doesn't actually work. If you uncomment it, you get:

  Specified mail user agent is not supported; exiting.
