Comments template mis-named variable

[filosofo]

The comments_template function declares a global '$comment' variable that it never uses.

It should be '$comments', not '$comment'.

$comments doesn't have to be global, as the comments template is included from within the function.

[filosofo]

True, now that there's the 'comments_array' filter, '$comment' can just be deleted.

Turns out there were a bunch of unused globals. Attaching patch to remove all unused ones. Not high priority to install patch.

Remove unused globals in comments-template function

Some templates may rely on these variables being there in the global scope, so wontfix. Also, the default theme itself breaks if you take some of those variables off of the global declaration.
