Bug#168500: dpkg: --help show unpaired pairs

[Dan Jacobson <jidanni@dman.ddts.net>]

Package: dpkg
Version: 1.9.21
Severity: minor

Upon --help we see:

Use dpkg -b|--build|-c|--contents|-e|--control|-I|--info|-f|--field|
 -x|--extract|-X|--vextract|--fsys-tarfile  on archives (type dpkg-deb --help.)

this should be changed so it is clear if the whole 2 lines refer to
archives, or just the last item.

also we see what are apparently pairs of items, but separated with the
same "|" as if they were independent.  Please pair them up better.
