Yes, that's more-or-less what I had in mind. I have some comments about the
implementation, but none of them are fundamental, I think:
- add "windows" to the function name somewhere
(`GetFlattenedWindowsCommandString`?, `GetWindowsCommandString`?, ...), as
function uses quoting style which is specifically meant for windows, and is
unlikely to be correct elsewhere
- drop the `if (m_entries[i].quote)` branch. You don't need it here, and I
don't believe it will be correct anyway, because all it will do is cause
`llvm::sys::flattenWindowsCommandLine` to add one more quote level around that
and escape the quotes added by yourself
