Autodetection doesn't recognize commands about google-code-prettify HOT 1 OPEN

This is keyword detection in the default language gone awry since '-' is 
considered a token breaker in most languages.

Thanks for taking the time to write up

Yeah, the default mode does a crap job with some shell-constructs.  The problem 
with '/' handling is that perl,JS,etc. use it for regexs and I've never come up 
with a good heuristic that fixes paths in shell languages without breaking JS 
in horrible ways.  It needn't be multiline except for perl obviously.

Since shell languages are so different, at a token level, from C style 
languages, they're likely to remain second class citizens.  Is specifying 
lang-sh or lang-bsh problematic?  If so, would it remain problematic if issue 
224 were implemented?
