It's not `skipped'. The partial match gets inserted before you go back to
line editing, when you can actually do something with it. There's no real
good HCI reason to insert it first only to have it scroll off the screen
as readline displays the possible matches, then insert it again before
going on. And say you decline to see the possible matches -- the partial
match gets inserted before you go back to editing anyway.
