+2018.01.29 - GNU nano 2.9.3 "Córdoba" fixes a segfault with trimblanks
+             that could occur when a typed space caused the word after
+             it to be pushed to the next line.  It further makes macros
+             work also when your keyboard still emits escape sequences,
+             adds the options -M and --trimblanks for the command line,
+             recognizes key combos with Shift on a few more terminals,
+             no longer shows dots in certain prompt texts when visible
+             witespace is turned on, fixes two corner cases when doing
+             replacements in a marked region, allows to open a named
+             pipe again when using --noread, and accurately detects
+             a needed color change when a line contains a start match
+             but not a corresponding end match any more.  Plus some
+             other small fry.

 <h2><a name="1.3"></a>1.3. Why the name change from TIP?</h2>
 <blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program &quot;establishes a full duplex terminal connection to a remote host&quot;, and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>
