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.

GNU nano is a simple and easy-to-use editor for on the terminal.

A concise overview of nano's shortcut keystrokes:

The tarball and its signature are here:

Specific bugs that were addressed in this release:  (document minus number after + 
[request])  (a <Tab> indented an empty selection)  (newer gcc gave some warnings)  (build failure on macOS)  (unhighlighted ^/ in help text)  (justification failed for mixed blanks)  (recognize more shell files [request])  (space after line number was colored)  (text could disappear upon autowrap)  (autowrap could fail with --autoindent)
