This gives you the chance to do something else with it, too - save it
under a second name, too, or perform some other action form your
Download Options menu.

You gotta admit that 680Mb AND your remote-mount setup is an unusual
situation... Lynx deals with it, but isn't exactly optimized for
this situation.

True (and I think this still isn't even reliably detected).

It would have removed it eventually, when exiting at the latest.

If you need to do this frequently, consider using a mechanism different
from the default builtin "Save to disk" implementation (which isn't
optimal for your situation).  A DOWNLOADER in lynx.cfg which does a
mv, probably after prompting for a name, should do the trick.
