Title:
apt fails to verify keys when Dir has space, and set via cmdline
Status in apt package in Ubuntu:
Fix Released
Status in apt source package in Xenial:
Fix Committed
Status in apt source package in Yakkety:
Fix Committed
Bug description:
When Dir has a space, and it is set via APT_CONFIG file, keys are found and
validated correctly.
When Dir is set without a space via cmdline, keys are found and validated
correctly.
When Dir is set with a space via cmdline, keys are not found and repositories
are not verified.
[Test case]
Please see attached reproducer, which works on xenial system (gpg1) but not
on zesty system (gpg2)

[Regression Potential]
The fix changes the code to generate quotes in the Commmandline:AsString
option, which dumps the command line for logging purposes. This was not
parseable before, causing the file to be rejected, so what can happen is that
something now works that did not before.
