<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Activity: Fix activity comment deletion when comment ID equals `0`.
In <a href="http://buddypress.trac.wordpress.org/ticket/7394">#7394</a>, non-existent activity ID lookups now default to zero, instead of
the ID that was passed. For example, `$a = new BP_Activity_Activity( 99 )`,
`$a->id` now equals `0` instead of `99`.
This is logistically correct; however, this raised a bug with
`bp_activity_delete_comment()` when passing `0` as the comment ID, which
could potentially delete all activity comments in the database.
Props Maniou.
Fixes <a href="http://buddypress.trac.wordpress.org/ticket/7450">#7450</a> (2.8-branch)</pre>
