[Bug 1336833] [NEW] a2ensite fails if the conf filename contains whitespace

[Chris Drost]

Public bug reported:

Package version tested: 2.4.7-1ubuntu4

Expected behavior: site names should be whitespace-tolerant.

[Side note: site names should probably also not require the .conf
extension, as there should be no other normal files in sites-enabled/ --
just filtering out directories (for version control systems which
wrongly version sites-enabled rather than sites-available) should
suffice. This also eliminates the complicated logic where a2ensite looks
both for "$1" and "$1.conf", unless we want to keep that for historical
compatibility reasons. ]

Observed behavior: a2ensite breaks when there is whitespace in a site
name.

Steps to reproduce:

$ sudo su -
# cd /etc/apache2/sites-available
# cp -a 000-default.conf '001 filename with whitespace.conf'
# a2ensite '001 filename with whitespace.conf'
ERROR: Site 001 does not exist!
ERROR: Site filename does not exist!
ERROR: Site with does not exist!
ERROR: Site whitespace does not exist!

** Affects: apache2 (Ubuntu)

         Status: New
