[Nano-devel] redoing the insertion of a file fails

[Benno Schulenberg]

When having undone the reading in of some file into another, and
then trying to redo this, results in an "Internal error" warning.

To reproduce, do 'echo echo >echo', then run nano an type:

^R  echo  <Enter>  M-U  M-E

[ Internal error: can't match line 2.  Please save your work. ]

This happens in current SVN, but also in 2.3.4 (which I've still
lying around), but not in 2.2.6 which works fine in this case.
