It doesn't align anything -- any allocations are already aligned to
whatever multiple is required -- it just shrinks the allocated space.

Nano would crash straight afterward if any of these asserts would fail,
so they don't add anything.  A few others are simply superfluous.

The fsfromline() function is mostly used by the undo functions, which
are not present in the tiny version.  It is also used by the comment/
uncomment feature, but this feature cannot be enabled when --enable-tiny
is in effect.

Achieve this by eliding two conditions from the inner loop,
which is possible because 'end' will never be NULL.

Convert digits() to take a ssize_t instead of an int, since it's
used on ssize_t line numbers.  And properly use the long modifier
when displaying a line number.

Also, conditionalize the digits() prototype.

The functions read() and fwrite() take size_t, not ssize_t.

And line numbers in the file should be displayed as a long type instead
of an int, since the effective type of ssize_t is not int, but long.

It can be activated with --linenumbers on the command line or with
'set linenumbers' in a nanorc file, and it can be toggled with M-#.

And also case-sensitive searches, backward searches, and searching again.

Mentioning "GNU nano" instead of "This program" and referring to the
website instead of to a postal address.

This fixes https://savannah.gnu.org/bugs/?48660.

This allows the user to specify which other characters, besides the
default alphanumeric ones, should be considered as part of a word, so
that word operations like Ctrl+Left and Ctrl+Right will pass them by.

Using this option overrides the option --wordbounds.

This fulfills https://savannah.gnu.org/bugs/?47283.

To make nano save its modified buffers when it runs out of memory.

It is easy to type beside the comma key and hit instead "m" or ".", so
accept also these as a separator between line and column number.  And
when being generous anyway, also accept space, slash and semicolon.

This fulfills https://savannah.gnu.org/bugs/?48305

When parsing a line and a column number, of course the found values
need to be passed back, otherwise it would be pointless to parse them.

If during startup there are multiple error messages, currently only the
last one remains and can be read.  To improve on that, introduce a short
pause between error messages -- even if it's not enough to read them all,
at least the user will be aware that there are multiple ones.

This also causes a few error messages to beep that currently don't beep,
such as when a file is unwritable.

When verifying that a match is a separate word (during spell checking),
instead of first copying out the word, then passing the word, and then
measuring its length, just pass its length straigtaway.

Nano doesn't start doing anything with the edit window or the keyboard
until all files have been read in or a blank buffer has been opened, so
the case of openfile->current == NULL will never occur.

Also correct the comment -- because with multibyte characters, it is
very well possible that the screen column corresponding to current_x
is smaller than current_x itself.

of the environment (which can lead to a root-owned .nano/ directory in
the invoking user's home directory).  This addresses Ubuntu bug #1471459.
