Documentation:
Alist mapping fringe mode names to fringe widths.
Each list element has the form (NAME . WIDTH), where NAME is a
mnemonic fringe mode name and WIDTH is one of the following:
- nil, which means the default width (8 pixels).
- a cons cell (LEFT . RIGHT), where LEFT and RIGHT are
respectively the left and right fringe widths in pixels, or
nil (meaning the default width).
- a single integer, which specifies the pixel widths of both
fringes.
