Bug#1020760: apt-file: not clear how to do EOL matching

[Curt Sampson <cjs@cynic.net>]

Package: apt-file
Version: 3.2.2

It's not clear how to anchor a non-`-F` search to end of line. I've
tried adding a dollar sign at the end (e.g. `apt-file search
'n/bash$'`, `apt-file search n/bash\$`) but that doesn't appear to
work. The manual page doesn't actually explain what a "pattern" even
is. It should be updated to document the pattern language and,
ideally, explain this particular point if it's possible to do this
with the pattern language.
