Obstructed update prevents property deletion on update

[Ross Mark <ro...@controllingedge.com.au>]

This bug has surprised me a few times where two working copies of the 
same repository would have different properties but I have finally found 
a recipe that works to re-create the problem.

The basic problem is when a directory has a property. You delete the 
property and add a file. In a second working copy also create a file of 
the same name. When you do an update in the second working copy it will 
fail due to a obstructed update. If you delete the obstructed file and 
rerun the update the property will not be deleted. If you delete the 
whole directory and rerun the update then the property goes away.

It sound quite confusing but the attached script should demonstrate it 
easily.

I've tested the script on both 0.33.0 and 0.34.0.

The only reason I found this is I use properties to maintain symlinks in 
directories and when I converted a symlink to a file the symlink would 
not disappear as the property was not being deleted in the WC even 
though it was in the repository.

I hope someone can use this script to track down the actual problem.

Yes, this is a real bug.  I've filed an issue for you (1672) and added 
some comments.  Thanks for your excellent reproduction recipe!

Just wondering if I should file an issue report for this bug. I was 
originally waiting to see if someone else confirmed this was a bug or I 
was just doing something funny.
