This could be simplified to:
(setq url (string-trim url))

And I'm not sure about the logic -- even stripping the leading spaces
seems dubious. The function is supposed to perform expansion of URL
(which may be a fragment) to BASE, and it's not supposed to do any DWIM
stuff.
What's the use case for stripping spaces? (Which are valid enough
characters in URLs in some (pre-encoding) cases.)
