I started emacs with -Q, typed M-x eww RET http://google.com RET, and saw

Debugger entered--Lisp error: (void-function fringe-columns)

Also first line of doc should be a complete sentence.
Also doc basically just reiterates the code.
Something like "Return non-nil if there's a fringe." would be more typical.

This is wrong when ‘fringe-columns’ is unbound and a fringe is present.
The right solution is to
(require 'fringe)
in ‘shr-mode’ as you proposed earlier.

Why would that happen? fringe.el is preloaded when GUI frames are
supported, and if not, there are no fringes. What am I missing?

What if the user doesn't want fringes in her sessions?
