 The UTF-8 patch introduces this regression: Ctrl+Left and Alt+Backspace
 proceed one more character than they should.

 (Consistently with unpatched mc, bash, and probably lots of other tools,
 Alt+Backspace should remove a sequence of non-alphanumeric characters
 followed by a sequence of alphanumeric ones, but instead it removes one
 more non-alphanumeric character at the end. Similar for Ctrl+Left.)

 Trivial patch is attached. I've created this patch years ago and posted to
 mc-devel; probably it's already included in some major Linux distributions
 as well.

 Please apply this fix in your UTF-8 patch. Thanks!
