The "-LA" parts sounds like a gamle to rely on as its not part of any
standard.

Right, that's actually what STAT does, -LA is probably just a system- specific
variant of it.

Yes, as long as you still ask for a file transfer as a file transfer in
regular FTP lingo means a separate connection for the data. You can set
CURLOPT_NOBODY to avoid that.

Isn't that contrary to the intent of and the exact PRET specification?

Apparently it's not possibly due to it not requiring PRET. But I must admit I
don't understand the logic for that, so I'm not really sure what the exact
best fix or improvement would be there.
