Re: Function editing and line editing have inconsistencies.

I would suggest looking at IBM APL2 and just do what they do.

Hi,

There are two inconsistencies (and slightly annoying) when editing:

1 - is a small inconsistency when deleting lines in editor mode.

     ∇X[⎕]
[0]   X
[1]   a
[2]   b
[3]   c
[4]   d
[5]   e
[6]   f
     ∇
[7] [∆1-3]   the editor only deletes lines 1 and 2
[6] [⎕]
     ∇
[0]   X
[3]   c
[4]   d
[5]   e
[6]   f
     ∇
[7] [∆4-7]   but the editor complains, if I want to delete the last line
∇-command failed: Bad line number N in [M∆N]
[7] [∆4-6]  again last line is being excluded from delete
[6] [⎕]
     ∇
[0]   X
[3]   c
[6]   f
     ∇
[7] [∆6]    need to delete last line in an additional step.
[7] [⎕]
     ∇
[0]   X
[3]   c
     ∇

Expected: delete lines x to y including line y in [∆x-y]


2 - moving cursor to previous line(s) skips most recent entry

enter:
       123
123
       456
456

cursor up - display entry line 456
cursor up - display entry line 123
cursor down - display entry line 123
cursor down - display current entry line
cursor up - display line 123  - should be line 456

In general:
after ENTER, the cursor moves one line up
after a CURSOR move up/down, the cursor moves two lines up.
This is also true during function editing.

Expected: cursor move should be line by line.
