Dear Maintainer,

`apt install git devscripts` in a clean trixie dist pbuilder environment and
see this:

...
Recommended packages:
  dctrl-tools                lintian          unzip
pristine-tar                libxstring-perl
  dput                       lzip             wget                       less
libdata-dump-perl

Are those logical-or vertical bar in output intentional? Looks like a parsing
bug to me, because of the column display the logical condition has lost context
and does not make sense to show the user. If you want to show these in a
meaningful way then after all the n-columns output of the simple non-logic-
encumbered keys, have a single-column listing one-per-line of the more
complicated keys.
