from the gitignore manpage:
 >> If the pattern ends with a slash, it is removed for the purpose of 
the following description, but it would only find a match with a 
directory. In other words, foo/ will match a directory foo and paths 
underneath it, but will not match a regular file or a symbolic link foo 
(this is consistent with the way how pathspec works in general in git). <<

Doesn't this mean, that if I say:
vendor/
matches the directory and ( recursively ) the paths underneath it.?
And, consequently:
!vendor/
inverse the exclusion for vendor ( that is: include ) and everything 
that is contained in it ? ( This is obviously not the case, but this is 
what I would expect )

This works for me ( I have indeed distributed them over several dirs )

At least it seams to work here ..
