Abstract FilePath Proposal

[David Turner]

One tiny amendment to a comment(!) in the non-normative(!) code in Phase 3:

data WindowsFilePath = WFP ByteArray# -- UTF16 data


If a Windows file path is valid UTF-16 then it is displayed as such in the
GUI, but if not it's still a legal file path. It really is just wchar_t[]
data:

data WindowsFilePath = WFP ByteArray# -- wchar_t[] data as passed to syscalls


This seems to be the source of some confusion.


Cheers,


David
