[ANNOUNCE] nano-4.1 is released

[Benno Schulenberg]

2019.04.15 - GNU nano 4.1 "Qué corchos será eso?"

• By default, a newline character is again automatically added at the
  end of a buffer, to produce valid POSIX text files by default, but
  also to get back the easy adding of text at the bottom.
• The now unneeded option --finalnewline (-f) has been removed.
• Syntax files are read in alphabetical order when globbing, so that
  the precedence of syntaxes becomes predictable.
• In the C syntax, preprocessor directives are highlighted differently.
• M-S now toggles soft wrapping, and M-N toggles line numbers.
• The jumpy-scrolling toggle has been removed.
• The legacy keystrokes ^W^Y and ^W^V are recognized again.
• Executing an external command is disallowed when in view mode.
• Problems with resizing during external or speller commands were fixed.


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