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.
On a freshly installed system, or for a new user, the default
XDG data directory may not exist yet. So, create it when not.

When a file is closed with the cursor on line 1, column 1, this
position is not recorded in file-positions history file -- if a
record for the file existed, it is deleted. In the latter case
the history file needs to be saved, so that other instances of
nano will know about the deletion.
This fixes https://savannah.gnu.org/bugs/?52505.
Whenever a buffer is closed, check whether the positions file on disk
was modified, and if so, reload it. Then update the position for the
closed buffer and write out the positions file to disk.

When not finding a .nanorc file in the user's home directory, nano will
look for a nanorc file in $XDG_CONFIG_HOME and in the ~/.config/nano/
fallback directory. And when not finding a .nano/ subdir in the user's
home directory, nano will look for (or create) the history files in
$XDG_DATA_HOME or in the ~/.local/share/nano/ fallback directory.
This is a partial implementation of the XDG Base Directory Specification:
https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html,
for the purpose of reducing the clutter in a user's home directory, and
to make it easier to back up just the configuration files.

The functions to read and write history files will not even be called
when the home directory is missing, so there is no need to check for
that eventuality again.
Populating the search, replace, and execute lists makes use of the
function update_history() which sets history_changed to TRUE, which
meant that the search_history file would always get written even if
nothing had changed.
