Hi Stefan,

Huh, I don't know what you mean by that, svn_wc_adm_probe_open3()
doesn't have such an argument.

The test schedules A/B/E for deletion, which immediately removes
A/B/E/alpha and A/B/E/beta from the working copy. Your patch uses
svn_io_get_dirents(), which won't be able to find them. This means we
have to continue using svn_wc_entries_read(), and just copy externals
explicitly if ignore_externals is FALSE.
I committed a fix to /trunk in r25707 which solves this issue in the way
I described.
Thanks,
Vlad
