after having had some conversation with Florian by private mail, we
came to the conclusion that his bug report was caused by the following
two real issues:

* The documentation on https://aptitude.alioth.debian.org/ only covers
  the newest version of aptitude. We might want to put up
  documentation also for other versions in currently supported Debian
  releases.

* Even on Debian unstable, "aptitude -F '%X' search '?installed'" just
  exits with return code 255, but gives no error message at all and
  hence causes confusion about what happened if a user tries escape
  sequences only supported by newer versions of aptitude or if there's
  a typo in an escape sequence.

The latter definitely should be fixed in aptitude. The former is a
nice to have in our documentation update infrastructure at
https://anonscm.debian.org/cgit/aptitude/aptitude-documentation-fetcher.git/
