accessing directories with embedded whitespace gives error

[felix winkelmann]

Accessing an URL like "​http://.../foo bar" gives this error:

Error:
bad argument type - not a structure of the required type
#f
URI-common

        Call history:

        reverse

Accessing a file under that directory works fine.

Fixed in [18361]. It was a very stupid mistake. Thanks for catching this, Felix!

I've also tagged release 4.6 as this is a serious enough bug to warrant a release.
