I knew we got --add-architecure and --remove-architecture. I hadn't
realised that --foreign-architecture was superceded.

Agreed - I thought it was probably different in the Debian version,
given the code changes in this area.

Title:
  does not allow whitespace on end of foreign-architecture config lines

Status in “dpkg” package in Ubuntu:
  New

Bug description:
  dpkg version 1.16.1.2
  If your dpkg config contain a line like:

  "foreign-architecture i386 "
  i.e with a space on the end of the line
  dpkg issues a warning:

  dpkg: warning: ignoring option --foreign-architecture=i386 : character
  ` ' not allowed

  it is reading the architecture as "i386 " which is perhaps a bit dim.

  To reproduce this my config in /etc/dpkg/dpkg.cfg.d/multiarch was:

  foreign-architecture i386
  foreign-architecture armel

  It does not happen if there is no newline after the "i386 " so you
  need either a second config line or a newline to produce the warning.

  And the warning comes in this part of the sequenmce when installing a
  new packge:

  # apt-get install grep-dctrl
