Please do not use "s" dependency

[thierryvolpiatto]

I see calls to s-replace-regexp, isn't this the same as replace-regexp-in-string?
One call to s-replace that tries to remove the dir part of a filename, please replace this with a regular emacs command e.g. file-name-nondirectory.
So no need to use a whole package as dependency for 3 or 4 calls of functions that can be replaced by emacs builin functions.
