It actually happened to me, so please trust me that it's not a legend.
Yes, I could fix it with hg commands, and a lot of text editing.
It took me a day, I considered the repository corrupted so that I
actually had to branch from the last ok revision, and redo all checkins
since (I also discarded changes which I didn't chose to redo). It was
a real catastrophe to me.

Since the changes actually changed all lines, "hg blame" became useless,
which was unacceptable.
