Expand abbr explicitly (#5762) 
* Add "expand-abbr" bind function

This can be used to explictly allow expanding abbreviations.

* Make expanding abbr explicit

NOTE: This accepts them for space only, we currently also do it for \n
and \r.

* Remove now dead code

We no longer trigger an abbr implicitly, so we can remove the code
that does it.

* Fix comment
