Function uriToFsPath

src/pathCommands.ts:167–185

* Compute `fsPath` with slash normalized to `/` for the given uri. * * This is what vscode uses internally to compute uri.fsPath; however, * backslash conversion for Windows host is removed, and drive letter is always normalized to uppercase. * * The problems with the internal `uri.fsPath`: *

(uri: Uri)
