I'm running Mercurial Distributed SCM (version 5.6.1)

This repository is just a personal repository running on my desktop
(xubuntu Linux) machine.  It's not being cloned from anywhere.

The 'bison' subdirectory which has the problem was copied from an
Android phone running termux, I think something funny must have
heppened while I was setting this up.

As I said, fortunately there was very little data in these additions
so I have simply restored from the latest backup that had no mercurial
errors and sorted things out from there.  It only took a short while,
I run hourly and daily incrmeental backups so finding all the changes
I needed to re-add wasn't too difficult.

It would be handy to know how to 'mend' such an error though if it
ever happens again.  (I still have the broken repository so I can try
the 'mend' on that).
