[PATCH] emacs: Remove "f" dependency

[Philip K]

The "f" library is a rather thin translation layer for already
existing Emacs functions. Most functions directly map to an already
existing function (eg. "f-no-ext" and "file-name-sans-extension"). For
this reason, removing "f" comes at no cost while reducing the number
of dependencies one has to count on and the user has to install.
