[ANNOUNCE] nano-5.0 is released

[Benno Schulenberg]

2020.07.29 - GNU nano 5.0  "Among the fields of barley"

• With --indicator (or -q or 'set indicator') nano will show a kind
  of scrollbar on the righthand side of the screen to indicate where
  in the buffer the viewport is located and how much it covers.
• With <Alt+Insert> any line can be "tagged" with an anchor, and
  <Alt+PageUp> and <Alt+PageDown> will jump to the nearest anchor.
  When using line numbers, an anchor is shown as "+" in the margin.
• The Execute Command prompt is now directly accessible from the
  main menu (with ^T, replacing the Spell Checker).  The Linter,
  Formatter, Spell Checker, Full Justification, Suspension, and
  Cut-Till-End functions are available in this menu too.
• On terminals that support at least 256 colors, nine new color
  names are available: pink, purple, mauve, lagoon, mint, lime,
  peach, orange, and latte.  These do not have lighter versions.
• For the color names red, green, blue, yellow, cyan, magenta,
  white, and black, the prefix 'light' gives a brighter color.
  Prefix 'bright' is deprecated, as it means both bold AND light.
• All color names can be preceded with "bold," and/or "italic,"
  (in that order) to get a bold and/or italic typeface.
• With --bookstyle (or -O or 'set bookstyle') nano considers any
  line that begins with whitespace as the start of a paragraph.
• Refreshing the screen with ^L now works in every menu.
• In the main menu, ^L also centers the line with the cursor.
• Toggling the help lines with M-X now works in all menus except
  in the help viewer and the linter.
• At a filename prompt, the first <Tab> lists the possibilities,
  and these are listed near the bottom instead of near the top.
• Bindable function 'curpos' has been renamed to 'location'.
• Long option --tempfile has been renamed to --saveonexit.
• Short option -S is now a synonym of --softwrap.
• The New Buffer toggle (M-F) has become non-persistent.  Options
  --multibuffer and 'set multibuffer' still make it default to on.
• Backup files will retain their group ownership (when possible).
• Data is synced to disk before "... lines written" is shown.
• The raw escape sequences for F13 to F16 are no longer recognized.
• Distro-specific syntaxes, and syntaxes of less common languages,
  have been moved down to subdirectory syntax/extra/.  The affected
  distros and others may wish to move wanted syntaxes one level up.
• Syntaxes for Markdown, Haskell, and Ada were added.
