In the preceding commit, open_buffer() was changed so that it gets
told whether to load into a new buffer or not, so it is no longer
needed to convey this information through a flag.
This fixes a regression introduced by commit 54103d8e: a crash that
can be triggered by running 'nano --restrict' and pressing <Insert>.
This addresses https://bugzilla.redhat.com/1558532.
As, since commit 0e30177d, the scrollup and scrolldown commands
no longer intend to move the cursor, they should not be seen as
movement functions.
Also, it is not guaranteed that functions are ordered in the same
way in the binary as in the source code, so an ordered comparison
of function pointers will not always work.
This fixes https://savannah.gnu.org/bugs/?53333.
This assumes that all movement functions are located together,
starting with to_first_line() and ending with do_right().
This fixes https://savannah.gnu.org/bugs/?53195.

The implant() function itself cannot be bound to anything, so it
is not in the linked list of functions -- trying to find it would
lead to a NULL pointer, and thus to a segfault.
This fixes https://savannah.gnu.org/bugs/?53233.
Instead of always calling sctofunc(), it is now only called when
in view mode OR when (after the keystroke's function has been run)
no need for a refresh has been established yet.
When 'refresh_needed' is already TRUE, there is no need any more
to check whether it should be set.
[Those first two calls are leftovers from before the time that
reset_multis() morphed into check_the_multis().]
When characters are added via Verbatim Input or by pressing <Tab>,
the prepend flag should be retained, just like when characters are
typed directly.
This fixes https://savannah.gnu.org/bugs/?52956.
In this way a single keystroke can produce a fragment of text or a
series of commands, or a mix of the two. It is like a prerecorded
macro.
This fulfills https://savannah.gnu.org/bugs/?52931.
Each leading tab is converted to two tabs, and any leading four spaces
is converted to one tab. The intended tab size (for keeping most lines
within 80 columns) is now four.
When unindenting/uncommenting affected the bottom line of the marked
region, keep affecting this line also during subsequent consecutive
indenting/commenting.
This fixes https://savannah.gnu.org/bugs/?52718.
The function get_keycode() should never return zero -- it should
return either the code from ncurses or the given fallback code.
This fixes https://savannah.gnu.org/bugs/?52682.
In this way we can delete things on the current line with ^K (after
Shift-selecting some text) without nano misdetecting a line change,
This fully fixes https://savannah.gnu.org/bugs/?52576.
Only when the cursor has moved off of the currrent line do we stop
prepending wrapped words to the next line.
This partially fixes https://savannah.gnu.org/bugs/?52576.
