Hi,
(require 'shr)
(let ((shr-base (shr-parse-base ".")))
(shr-expand-url "www.example.com"))
errors with
Debugger entered--Lisp error: (wrong-type-argument char-or-string-p nil)
url-scheme-get-property(nil expand-file-name)
url-expand-file-name("www.example.com" "./")
shr-expand-url("www.example.com")
(let ((shr-base (shr-parse-base "."))) (shr-expand-url "www.example.com"))
(progn (require (quote shr)) (let ((shr-base (shr-parse-base ".")))
(shr-expand-url "www.example.com")))
eval((progn (require (quote shr)) (let ((shr-base (shr-parse-base ".")))
(shr-expand-url "www.example.com"))) nil)
eval-expression((progn (require (quote shr)) (let ((shr-base (shr-parse-base
"."))) (shr-expand-url "www.example.com"))) nil nil 127)

Regardless of whether it makes sense or not, it'd be nice if Emacs could
