Summary
Fix percent-encoded Windows drive separators in
file:URIs so paths such asfile:///C%3A/Temp/example.mdresolve toC:\Temp\example.mdinstead of retaining a leading separator that causes the current drive to be prepended again.url2pathname()checks for a DOS drive before percent-decoding the path. When the colon is encoded, that check misses the drive and leaves a leading separator in the decoded Windows path. The conversion now removes that separator only when the decoded path has Windows drive syntax; POSIX and UNC paths are unchanged.A platform-independent regression test emulates Windows path handling and verifies the encoded URI result.
Fixes #2208
