 Eshell taking long time to enter directory  after TAB completion

I was probably wrong about the apparent total unsuitability of the markers.

I just realised the issue with argument deletion can be fixed trivially:

It works. I don’t know if it also breaks anything.

The problem with new line characters remains, but it really seems to be a different issue. In fact, can multi-line completion be useful in some cases? Maybe it is eshell that should tell the completion mode to stop when a command has been entered. I want to know how SPC works in the current scheme. RET should do the same in eshell.
