[Bug 1628654] Re: apt-mark's regex matching seems odd

[Julian Andres Klode]

To clarify what happened here:

(1) *vcard is an fnmatch() expression matching 2vcard

(2) vcard* is an unanchored regular expression matching 2vard.

Title:
  apt-mark's regex matching seems odd

Status in apt package in Ubuntu:
  Triaged

Bug description:
  [ 12:06PM 4528 ]  [ bdmurray at speedy:~/source-trees/ubuntu-release-upgrader/upstream ]
   $ apt-mark showmanual \*vcard
  2vcard
  [ 12:07PM 4529 ]  [ bdmurray at speedy:~/source-trees/ubuntu-release-upgrader/upstream ]
   $ apt-mark showmanual vcard\*
  2vcard

  I was surprised the latter option found a match.

   $ apt-cache policy apt
