However, filepath-bytestring is still in Setup-Depends.
That's because Utility.OsPath uses it when not built with OsPath.
It would be maybe possible to make Utility.OsPath fall back to using
filepath, and eliminate that dependency too, but it would mean either
wrapping all of System.FilePath's functions, or using `type OsPath = FilePath`
Annex.Import uses ifdefs to avoid converting back to FilePath when not
on windows. On windows it's a bit slower due to that conversion.
Utility.Path.Windows.convertToWindowsNativeNamespace got a bit
slower too, but not really worth optimising I think.
Note that importing Utility.FileSystemEncoding at the same time as
System.Posix.ByteString will result in conflicting definitions for
RawFilePath. filepath-bytestring avoids that by importing RawFilePath
from System.Posix.ByteString, but that's not possible in
Utility.FileSystemEncoding, since Setup-Depends does not include unix.
This turned out not to affect any code in git-annex though.

These are too widly used for other things to make sense to export OsPath
versions of them. And OsString also provides them and gets imported
qualified when needed.
If the filepath starts with something that is not valid utf-8, it would
have returned "". And if the filepath was all non-valid utf-8, it would
also return "".
I hope that the windows test suite failure on appveyor was fixed by
updating to a newer windows there. I have not been able to reproduce
that failure in a windows 11 VM run locally.
When an UNC-style path is passed into openTempFile, the returned file
starts with that same style of path. Which can cause problems, eg piping
that filename to git failed. So, convert the output filename to be
relative to the input temp directory.

After recent changes to use OsPath, test suite fails on windows with:
Exception: Uneven number of bytes: 5. This is not a Word16 bytestream.
Hopefully this fixes it. The innefficiency of the conversion is
unfortunate.
Taking a ShortByteString and using OverloadedStrings should avoid it
being converted from a String.
The reason there is no IsString instance for OsPath is presumably the
bad behavior of IsString for ByteString on unicode btw. But
literalOsPath won't be used with unicode in git-annex.
