Subject: Process directories unconditionally.
X-Git-Url: https://git.rkrishnan.org/maximilian?a=commitdiff_plain;h=11d28263d1f3eb195c65270dc57b1676a5a806fb;p=tahoe-lafs%2Ftahoe-lafs.git

Process directories unconditionally.
Also pass overwrite=False and suppress ExistingChildError when creating a
subdirectory, to avoid orphaning any existing directory.
