This PR was an effort to address #321 (ed_quoted_insert doesn't work
properly) but per the reporter it did not work correctly.
Moreover, it introduced a major regression: Shell job control stopped
working in all applications that use reline, notably IRB.
Bash and other shells send SIGTSTP in response to C-z to implement job
suspension. Handling SIGSTP opts out of this functionality. For a
line oriented terminal program this should be avoided (not to mention,
this behavior diverges from readline's)

* Test existing behavior
Typing Ctrl-D ends editing but typing <Del> does not.
Also renamed a test that is not testing ed_delete_next_char but
key_delete.
* Check if line empty first in em_delete
By distributivity of AND over OR, we can factor out this condition. This
will make the next commit simpler.
* Use em_delete in key_delete
When the editing mode is emacs, use `em_delete` in `key_delete`. We need
to add a condition though to `em_delete`, because it implements both
`delete-char` and `end-of-file`. We only want the `end-of-file` behavior
is the key is really Ctrl-D.
This matches the behavior of the <Del> key with readline, i.e. deleting
the next character if there is one, but not moving the cursor, while not
finishing the editing if there are no characters.

duplicated line.
(https://github.com/ruby/reline/pull/460)
* whole_lines should consider prev_line_index, and must not duplicate last_line
* Add test for lines passed to dynamic prompt proc
* Refactor whole_lines parameters used in test helper
* Remove whole_line's arguments
sequence) to check_multiline_prompt
(https://github.com/ruby/reline/pull/458)
* pass unmodified lines to check_multiline_prompt
* Add test to check that output modified by output_modifier_proc is not passed to prompt_proc
In some tests, the LineEditor#reset method is always called, but doesn't
need to set the signal handlers there, so cuts it out to a separate
method.

The number of lines below the cursor position was known by
"@rest_height" alone, but the problem was caused by adding
"lower_space". Remove "lower_space" as it is unnecessary.

fix https://github.com/ruby/irb/issues/308
This bug occurred when `dialog.width - calculate_width(s, true)` was negative.
When `dialog.width` is shorter than `old_dialog.width`, it calculates how much padding it has to do. However, there are cases where `s` is longer than `dialog.width`, as in the issue. In that case, `padding_space_with_escape_sequences` will crash.
Here, `old_dialog.width` is longer than `dialog.width`, so I changed the padding width to `old_dialog.width - dialog.width`.

Fixes a crash in IRB if a dialog is displayed and the default
external encoding is not UTF-8:
/home/jeremy/tmp/reline/lib/reline/line_editor.rb:731:in `write': U+2588 from UTF-8 to US-ASCII (Encoding::UndefinedConversionError)
