I think `unescapeSlashes` in D43002 was only a quick hack to allow copy-pasting
a command-line file name from LIT outputs into the VS debugger options dialog.
If the file name contains double quotes I would expect it to be converted as
you do, but double quotes cannot happen in file names on Windows. In theory one
could use the `S_OBJNAME` and `LF_BUILDINFO` records to repro a clang-cl build
command on Linux, but that seems improbable? (since the feature is meant to be
used on Windows)

Ok, we only have stuff like `rc.exe /l 0x0409` in our build scripts, the 0x in
front isn't consumed, I though it was mandatory.
