Support for :setf[iletype]

[robertquitt]

As I am mainly a user of vim, my instinct for changing filetype is using :setf. It would be nice if there were a way to open the "grammar menu" and set the Atom grammar immediately.

I am very new to the Atom editor, but I think this would be helpful. Hitting <C-L> is a bit counter-intuitive for me.

Here is the description of how :setf works from the Vim documentation. Basically, Atom's "grammar" is equivalent to Vim's filetype.

:setf[iletype] [FALLBACK] {filetype} :setf :setfiletype

Set the 'filetype' option to {filetype}, but only if not done yet in a sequence of (nested) autocommands. This is short for

:if !did_filetype()
:  setlocal filetype={filetype}
:endif

This command is used in a filetype.vim file to avoid setting the 'filetype' option twice, causing different settings and syntax files to be loaded.

When the optional FALLBACK argument is present, a later :setfiletype command will override the 'filetype'. This is to used for filetype detections that are just a guess. did_filetype() will return false after this command.
