Title:
  Multipath: underlying disks are listed for partitioning on systems w/
  26+ disks

Status in partman-base package in Ubuntu:
  Fix Released
Status in partman-base source package in Trusty:
  Fix Released

Bug description:
  [Impact]
  Systems with more than 26 multipath disks will see the underlying disks listed rather than included under the multipath device (which is a separate entry in the list). This affects any user trying to install on a system with more than 26 multipath disks.

  [Test case]
  Install Ubuntu using d-i on a system with more than 26 multipathed disks.

  [Regression Potential]
  Limited to multipath. This simply folds two spaces into one and accounts for extra spaces in the output of multipath -l when there are more than 26 disks (ie. when you start to see sdaa#), by adjusting the regular expression.

  ---

  On top of the fix in LP: #1430074, there's a minor bit missing.

  It doesn't hide all underlying disks in the partitioning dialog if
  there's 26+ underlying disks (i.e., enough for sdaa and so on to show
  up).

  It happens because, in that case, 'multipath -l' now puts 2 spaces
  betweek disk and major:minor for the sd[a-z] disks, and only 1 space
  for sd[a-z][a-z].

  Patch attached.
