When the keyboard buffer is empty, return a value that is not equivalent
to <Ctrl+Space>, so that typing a bunch of these while searching is going
on will not result in some of them getting executed afterward.
When doing for example: ^W xx ^R ^C ^W, the "xx" would again be shown
after the prompt. This is wrong -- when starting a new search, the
current answer should be empty.

Instead of weaving back and forth between do_search()/do_replace() and
search_init() every time that one of the options is toggled, just keep
looping in the latter function until the user presses <Enter>.
The weaving for the do_gotolinecolumn() function remains, but is
shortened to involve only search_init().
When we're just searching, we do want to report the occurrence at
the cursor (after coming full circle) as a match, so that we can
mention that this is the only occurrence. When replacing, we do
not want to replace this match twice.

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.
The pointer not being NULL is enough indication that the mark is set.
Also, rename the pointer from 'mark_begin' to simply 'mark', since
the former is kind of pleonastic.
When there are no help lines, there won't be any call to update the
actual contents of the bottom window, so... do it immediately after
blanking the row.

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.
After any replacements were made, the "not found" message is pointless
because it will be overwritten rightaway by "Replaced xx occurrences".
The message is confusing and annoying when using speech output.

Most people who make use of 'do_findprevious' and 'do_findnext'
will not make use of 'do_search' (the default binding of M-W),
so for them it is superfluous to remember the state of the
Backwards toggle in the Search menu. For the people that do
mix the usage of Alt+Up/Down with M-W, it means that M-W will
always search in the same direction as the last search. It is
a small change in behavior.
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.

When reducing the search string to at most half the screen width,
it should employ its width in columns, not its length in bytes.
Also adjust the type of a variable.
This fixes http://savannah.gnu.org/bugs/?52057.
When not using --smooth (nor 'set smooth'), and a line near or beyond
the end-of-file is addressed with the + command-line argument, then
center the cursor, just like Pico does -- so in the default mode,
nano is again more like Pico.
This partially addresses https://savannah.gnu.org/bugs/?51489.
spotlight() now displays softwrapped lines chunk by chunk instead of all
at once. Since softwrapped lines are no longer of constant width, the
latter approach would fail if softwrapping breaks the spotlighted text.
Instead of taking a string, spotlight() now takes the starting and ending
columns of that string. Also, its handling of softwrapped lines is now
split off into a separate function, spotlight_softwrapped().
get_chunk_row() replaces the formula "column / editwincols".
get_chunk_leftedge() replaces "(column / editwincols) * editwincols".
get_last_chunk_row() replaces "strlenpt() / editwincols".
get_last_chunk_leftedge() replaces "(strlenpt() / editwincols) * editwincols".
This prepares us for any changes in those formulas, and for more such
functions later.
