Brion Vibber 87786e84dd Revert r86764, r89134, r86827 -- added a second opaque boolean parameter to Linker::commentBlock() which appeared to mostly just turn it into Linker::formatComment().
commentBlock() exists for the sole purpose of embedding a comment into parentheses if it exists so you can append it to a line of text -- if you're not putting stuff in parentheses, don't use commentBlock() because you're not generating a parenthesized comment block.
Opaque boolean parameters are also very poor form, especially when tacking on multiple ones. There was already a nasty optional '$local' boolean param, forcing all uses of this other parameter to add *two* parameters, making illegible stuff like 'false, false'.
