["Steinar H. Gunderson" <sgunderson@bigfoot.com>]

Package: lintian
Version: 1.23.15
Severity: normal

I have the following changelog entry:

  * Remove evms-udeb and all traces of it in the build system.
    (Closes: #223995, #239892)

dpkg-parsechangelog parses this correctly, but lintian complains:

W: libevms-2.5: wrong-bug-number-in-closes #xxxxxx

N:   Bug numbers can only contain digits.
N:   
N:   Refer to Policy Manual, section 4.4 for details.

Policy 4.4, however, mentions a regex, and my closes line definitely
matches that regex. What's going on? Why isn't lintian using the regex
from Policy?
