Make PhutilDocblockParser slightly more liberal in finding "@special" annotations
Ref T988. XHProf has some docblocks like this:
/** * Blah blah blah, one space indent. * * @author two space indent */
This is slightly ambiguous with code blocks, but be more liberal in parsing it since we don't really create any ambiguity.
Test Plan: Unit tests.
