		as a String (e.g. in |expr5| with string concatenation
		operator) and to zero when used as a Number (e.g. in |expr5|
		or |expr7| when used with numeric operators). Read-only.

				*v:fcs_choice* *fcs_choice-variable*
v:fcs_choice
		What should happen after a |FileChangedShell| event was
		triggered.  Can be used in an autocommand to tell Vim what to
		do with the affected buffer:

		          the file was deleted).
		  edit    Reload the buffer and detect the
		          values for options such as
		          'fileformat', 'fileencoding', 'binary'
		          (does not work if the file was
		          deleted).
		  ask     Ask the user what to do, as if there
		          was no autocommand.  Except that when

		          will happen.
		  <empty> Nothing, the autocommand should do
		          everything that needs to be done.

		            changed and buffer is modified
		  changed   file contents has changed
		  mode      mode of file changed
		  time      only file timestamp changed
