Now you can have a look elsewhere in the buffer (and even delete
or paste stuff there) and when you return to the original line
and continue typing, any spillover from automatic hard-wrapping
will spill over onto the same line it spilled over to before.
You can even switch to a different buffer and return and continue
typing, and stuff will still spill over to the same line.
In the bargain, this gets rid of a bit of flag-resetting code
that was run for many keystrokes, in most cases needlessly.

The lack of initialization caused a nasty bug on some targets (such as
ARMv7) which would make it so that ^S would just say "Cancelled".
While x86 (both 64 and 32 bits) seems to initialize 'response' to zero or
a positive number, ARM does not, and there is usually a negative value in
its place, which triggers the 'if (response < 0)' check and, as a result,
the code says "Cancelled".

The user did not move the cursor nor intend to move the cursor, so
leave things as they are.

This function allows the user to "make space": annihilating lines or
regions while keeping intact for pasting the stuff in the cutbuffer
that was cut or copied earlier.

When --view is used without --ignorercfiles, the user could view
other files anyway if they had 'set multibuffer' in their nanorc.
So, just make this the default when --view is used, also because
"multibuffer" cannot be toggled once nano is running in view mode.
When the viewing of other files in view mode should not be allowed,
one should now additionally use --restricted.
When 'inhelp' is true, there are at least two buffers open: an
edit buffer and the help-text buffer.
And bottombars() already does a full refresh of the bottom window.
The crawl needs at least five rows to be perceived as a crawl, and
the widest line is 31 characters (ignoring translations, which might
be even longer). Formerly, when only two or three rows were available,
nothing was shown at all, which was puzzling. So, better do the credits
only when there is room enough for them, and print a message otherwise.
When switching to a different buffer, don't just show its name but
also the number of lines it contains. This is useful extra info.
Then use this same message when at startup multiple files are opened
and (after reading them all) we switch back to the first buffer.
(This loses, when multiple files are opened, the information about
format conversion that nano still shows when a single file is opened,
but... this bug has shown that people don't really look at this line
anyway, so... let it be. The info can still be seen when writing out
the file with ^O.)

Unlike glibc, which in getc() locks the file only when it is needed,
FreeBSD and Bionic libc will always lock the file, causing a massive
slowdown, as the system has to create and destroy a mutex each time
getc() is called.
Avoid that massive overhead by locking the file before starting to read
and unlocking it after reading is complete, and using getc_unlocked() to
read each byte. This makes reading on FreeBSD/macOS and Android anywhere
from 2 to 6 times faster, and on glibc roughly seventy percent faster.
This partially addresses https://savannah.gnu.org/bugs/?50406.
