If the user uses a single version of nano, they have no need for
--quiet.  If they do sometimes use an older version and don't want
to see the warnings, they can use 2>/dev/null (they could make an
alias for that and put it before the call of nano).

The user told nano to start, thus nano should *start* -- without
halting and without nagging the user.

Initialize 'breaking_col' to what it needs to be when the current chunk
consists of only a tab -- a tab that spreads across both start and end
of the chunk -- so that the last 'if' can move into the preceding one,
which allows the elision of 'char_len'.

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 key sequence ^R ^X M-F <Enter> would cause nano to abort, because
it would try to add an empty string to a history list.  (Furthermore,
simply don't execute an empty command, because it is pointless.)

And use a better word to describe the concise descriptions that
these constants refer to -- they are not messages.

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.

List "browser", "pageup" and "pagedown" in the manuals; the first
because it matches "speller", and the latter two because they are
what these functions are commonly known by.  The names "tofiles",
"prevpage" and "nextpage" are now undocumented, but they are still
recognized by the code, as they match the tags for these functions.

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.

This fixes https://savannah.gnu.org/bugs/?52246.

Adjust to the changed meaning of 'whereis': it is no longer do_search()
but do_search_forward().

Allow the user to record and run a single macro.  The default binding
for starting and stopping the recording is M-: (Alt + colon) and for
running the macro M-; (Alt + semicolon).

This fulfills https://savannah.gnu.org/bugs/?50314

It would be silly for ^W to do a backward search too after using ^Q
once.

^S will be the first thing people will try for saving a file,
and ^Q is somewhat mnemonic because it is to the left of ^W:
it searches backward.

Make these keystrokes available also in the tiny version.
