At syntax doesn't work when placed immediately after a parenthesis

edit

Specifically, this doesn't work:

(@qubit won't get a ping for this...)

Here's a more extensive test set of what does/doesn't work regarding @-syntax linking. As of 2013-03-19:

This set matches/links:

• @qubit jumped over the lazy dog
• "@qubit jumped over the lazy dog"
• '@qubit jumped over the lazy dog'
• ,@qubit stuck to that comma like glue
• Behold:@qubit
• @qubit.
• @qubit...
• @qubit,

This set does not match or link:

• (@qubit jumped over the lazy dog)
• [@qubit jumped over the lazy dog]
• {@qubit jumped over the lazy dog}
• |@qubit jumped over the lazy dog|
• --@qubit wished he had a real em dash, instead of just pretending with two hyphens
• @qubit)
• @qubit/@qubit
