Adds synopses for those commands missing them.
Moves all synopsis sections to code blocks. This improves the appearance, although highlighting as
fish code may not be the ideal appearance.
This exitted if the cursor was at the end of the line as well (i.e. if
delete-char failed). That's a bit too eager.
Also documentation, which should have already been included.
If we switch the bind mode, we add a "force-repaint" there just to
redraw the mode indicator.
That's quite wasteful and annoying, considering that sometimes the prompt can take
half a second.
So we add a "repaint-mode" function that just reexecutes the
mode-prompt and uses the cached values for the others.
Fixes#5783.
* 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
