Code formatting is just wrong (missing space) - thanks @txdv 

@saghul please refer to the commit https://github.com/andrewlow/node/commit/c1d565ba92ab1eb3c6950904653b8fb19b938405 which is a work-around for the lack of AF_UNIX socket introspection ability on AIX.

This is a trade-off between correctness and working code in the common cases. We are forced to guess as AIX simply doesn't have the same capability as other Unix in this area.
