This avoids a bunch of warnings when compiled with -pedantic:

	ISO C forbids comparison of ‘void *’ with function pointer

To prevent getting kicked out of it.

A shortcut's function must be among the existing ones, otherwise
nano's code is fundamentally broken.

Commit bb667beb removed do_gotolinecolumn_void() from the MWHEREIS
menu (replacing it with the empty flip_goto() function), so there
is no longer any need to check for this one special case.

A shortcut's function can never be NULL.

It is only ever set and never referenced.

Exclude the confusing, pleonastic 'sc' abbreviation from their names.

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.

That is, call display_string() just on the filename, not on the rest
of the prompt text.

And one for me, for the much changed keyboard stuff.

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.

In the tiny version, do_prompt() will now have an extra NULL
parameter, which will cost maybe twenty extra bytes of code.
That is acceptable when it saves thirty lines in the source.

The basic idea is that the cursor is always off, except when it needs
to be on: when waiting for text input, and in a few other cases: when
something was searched and found in the help viewer, and in the file
browser when option -g is in effect.

Without them, nano still compiles for me, with everything enabled,
even when using --enable-debug, --enable-utf8, and --with-slang.

Include the shortcut for 'Uncut' into most menus, and add an uncut
function for the status bar, so that it becomes possible to paste
the first line of the cutbuffer at any text-input prompt.

This matches the style in the rest of the code.

Add missing spaces, remove excess spaces, and
replace groups of indentation spaces with tabs.
