Bug#302031:

[Max Bowsher]

I have followed the procedure outlined by the submitter as closely as 
possible, and coded a reproduction script.

No data loss occurs for me - at the point where the sumitter writes "all of 
dir c, including the local modifications got erased", what happens to me is:

any files within dir c which contain local modifications are left on disc as 
unversioned files.

It is true that in such a state, the local mods are no longer in a 
version-controlled file, and so 'svn diff' will not display them - however, 
they remain present, and data is not lost.
