Bug#811206: I got -bash: /usr/bin/nano: No such file or directory with nano 2.4.3-1

[Benno Schulenberg]

After having just updated a system, it is best to run 'hash -r',
to tell the shell to forget everything it thinks to know about
paths.  After that, it should find nano again.  Logging back in
should work too.  If that does not solve it, please report back.
