bug#6480: 24.0.50; Value `default' for `fringe-mode'

["Drew Adams" <drew.adams@oracle.com>]

emacs -Q
 
The possible values for input to command `fringe-mode' are these:
 
`none', `default', `left-only', `right-only', `minimal' and `half'
 
These values need to be described in the doc string.  In particular,
`default', `minimal', and `half' are not obvious - especially `default'.
 
What is important about `default' is not that it is the default but that
it means show both left and right fringes.  It should be renamed `both'.
 
The doc string should say that the default width of 8 pixels is used
for all except `half', which uses 5 pixels, and `minimal', which uses 1
pixel.
 
I'd also suggest renaming `half' to `narrow', and perhaps
`(left|right)-only' to `(left'|right):
 
   both, narrow, minimal, left, right, none
