Yes, I completely agree.

I already tried that last week (and you are right), but decided to go
for the easy solution as the main inconsistency is indeed in
GNAT.Expect.Non_Blocking_Spawn. Fixing it there brings it in line with
the other Spawn functions in GNAT.OS_Lib and fixes the most frequent
case of spaces in pathnames ("C:\Program Files\"). It's in any case not
wrong to apply my suggested patch there.

If in addition, Ada.Command_Line was changed that even spaces in the
basename are taken care of, even better. But changing Ada.Command_Line
isn't an alternative but an addition to the suggested patch.
