[PATCH] Re: Directory becomes file when applying patch

From: Dmitry Pavlenko <pavlenko_at_tmatesoft.com>

Hello, Julian!
I've checked that the latest trunk version skips the directory in this case
(much better than making it a file). So I'm not sure if it is possible to turn
it into directory addition at all.

Anyway I've created a test for the case. I'm not 100% sure in the expected
output/disk/status of the test but from the first glance it looks ok.

The test fails because it expects a directory with a property to be created
but it is skipped.
