s[^\s*(.*)\b\s*$][$1]

Update: Corion rightly points out that this does not work correctly for lines where the last non whitespace character is a non-words character. Eg. 

    the quick brown fox (   \n
#                       ^

So, use s[^\s*(.*\S)\s*$][]; instead. It's slower, but still quicker than the FAQ method.
