The offending commit is 4314b8de "display: blank the status bar on a successful cut or paste".  That seems weird, but the commit changes a call of cut_text() to do_cut_text(...).  That causes the check at the start of cut_text() to be skipped.  :|

To reproduce, add the following two lines at the end of your ~/.nanorc:

  bind ^D cutwordleft main
  bind ^F cutwordright main

Then run:

  src/nano +1 NEWS

and type: ^D
See that the top right corner now says "Modified" even though nothing was deleted and the buffer has not been modified at all.

Now type: M-U M-/ ^F
See that the status bar says "[ Nothing was cut ]".  This is the right behavior.  ^D at start-of-buffer should behave the same.

Bug exists since nano-4.4.  Versions 4.3 down to 4.0 did the right things: they said nothing was cut.  Versions before 4.0 down to at least 2.7.4 simply did nothing, without giving any feedback.

Expected behavior: chopwordleft at the head of the buffer should not mark the file as modified and give the same feedback as chopwordright at the tail of the buffer.
