Bug report

Bug description:

On Windows, urllib.request.pathname2url() raises OSError when given a path with a colon in any position other than the second character. This excludes paths with NTFS alternate data streams, which are valid in other path-processing functions (e.g. in os.path and pathlib):

from urllib.request import pathname2url pathname2url(r'C:\foo:bar') OSError: Bad path: C:/foo:bar # expected: ///C:/foo%3Abar pathname2url(r'foo:bar') OSError: Bad path: foo:bar # expected: foo%3Abar
