nano: update to 4.8

2020.02.07 - GNU nano 4.8 "Jaška"
• When something is pasted into nano, auto-indentation is suppressed,
  and the paste can be undone as a whole with a single M-U.
• When a lock file is encountered during startup, pressing ^C/Cancel
  quits nano.  (Pressing 'No' just skips the file and continues.)
• Shift+Meta+letter key combos can be bound with 'bind Sh-M-letter'.
  Making any such binding dismisses the default behavior of ignoring
  Shift for all Meta+letter keystrokes.
• The configuration option --with-slang (to be avoided when possible)
  can now be used only together with --enable-tiny.
• A custom nanorc file can be specified on the command line, with
  -f filename or --rcfile=filename.

2019.12.23 - GNU nano 4.7 "Havikskruid"
• A <Tab> will indent a marked region only when mark and cursor are
  on different lines.
• Two indentations (any mix of tabs and spaces) are considered the
  same when they look the same (that is: indent to the same level).
• When using --breaklonglines or ^J, a line will never be broken in
  its leading whitespace or quoting.
• The keywords in nanorc files must be in lowercase.

2019.11.29 - GNU nano 4.6 "And don't you eat that yellow snow"
• The 'formatter' command has returned, bound by default to M-F.
  It allows running a syntax-specific command on the contents of
  the buffer.
• ^T will try to run 'hunspell' before 'spell', because it checks
  spellling for the locale's language and understands UTF-8.
• Multiple errors or warnings on startup will no longer slow nano
  down but will be indicated on the status bar with trailing dots.

2019.10.04 - GNU nano 4.5 "Košice"
• The new 'tabgives' command allows you to specify per syntax what
  the <Tab> key should produce: some spaces, a hard TAB, ...
• The output of --help is properly aligned again for all languages.
• <Tab> will indent a marked region also when M-} has been rebound.
