Hi,

# aptitude download dirmngr=2.1.18-8~deb9u3
Error: pattern not supported by this subcommand: 'dirmngr=2.1.18-8~deb9u3'

Although the command  actually called by 'aptitude  download' ('apt download')
handles it without problem:
  # apt download dirmngr=2.1.18-8~deb9u3
  Get:1 http://ftp.jp.debian.org/debian stable/main amd64 dirmngr amd64 2.1.18-8~deb9u3 [597 kB]
  Fetched 597 kB in 1s (857 kB/s)

Hi Arnaud,

Thanks for that bug report!

I can reproduce this on Debian Sid as well as on Debian 9 Stretch, but
not on Debian 8 Jessie. So it seems to be a regression introduced
between 0.6.11-1 and 0.8.7-1.

Manuel: I assume this can fixed by making that check only look for ~
at the beginning of the string or after blanks and exclamation marks.
(Or maybe just not after numbers and probably also not after letters.)
