Subject: (extract_archive): When marking a directory to be updated after
X-Git-Url: https://git.dogcows.com/gitweb?a=commitdiff_plain;h=6c9e824ce52554abd04bf4c7f8e20485ccbe2dc4;p=chaz%2Ftar

(extract_archive): When marking a directory to be updated after
symlinks, stat all directories after it in the delayed-set-stat
list too, since they will be checked after symlinks.
Add support for --overwrite-dir.
