>Description:
SUSV2 defines special handling of read-only directories.  cp should first create them writable (S_IRWXU set), copy the contents, then fix up permissions later.  Since rev 1.1, cp.c has attempted to do this, but does this in the wrong order (create-writable, set-read-only, copy-contents, oops).
>How-To-Repeat:
% mkdir a
% touch a/x
% chmod a-w a
% cp -R a b
cp: b/x: Permission denied
%
>Fix:
Gnu cp handles this by keeping a list of directory permissions to fix after all copying has been done.  Such a mechanism could also be used to close other outstanding PRs on cp problems (like preserving directory modify times).
