Properly match the rules "**/" and "!**/"

Browse Source 
When processing a rule that ends in a slash, we strip it off and set the
`is_only_dir` flag.  We then apply the rule that paths that aren't
absolute should be given an implicit `**/` prefix, while avoiding
adding that prefix if it already exists.

However, this means that we miss the case in which we had already
stripped off the trailing slash and set `is_only_dir`.  Correct this
by also explicitly checking for that case.

Fixes #649
