Bug#86923: Should be more finicky about filenames in /etc/apt/apt.conf.d

[Matt Zimmerman <mdz@debian.org>]

Package: apt
Version: 0.5.0
Severity: normal

Currently, ReadConfigDir seems to only exclude files with certain extensions
(.disabled, .dpkg-old, etc.).  It misses, in particular, vim .swp files (which
also start with a dot, and otherwise don't look like real config files).  This
causes bad things to happed if apt is run while a vim session is open on one of
the files in apt.conf.d.

Note that adding .swp to the list of forbidden extensions doesn't fix the
problem, as multiple sessions seem to get filenames ending in .swo, .swn, etc.
You could, however, fix things by ignoring all filenames starting with a dot.
It might be more sensible, however, to invert the check, and only pay attention
to files with a certain extension (say, .conf).
