SVN rev 194560 on 2009-06-20 20:44:27Z by jilles
Fix race condition in noclobber option.
Formerly, it was possible for the file to be created between the check if it
existed and the open; the contents would then be lost.
Because this must use O_EXCL, noclobber > will not create a file through a
symlink anymore. This agrees with behaviour of other shells.
