[wp-hackers] Upgrade instructions fatally flawed for Mac

There is a major bug in the upgrade instructions on
http://codex.wordpress.org/Upgrading_WordPress that can cause Mac users
to lose their data. This needs to be corrected. The problem is here:
Step 3: Overwrite Files
Get the latest and greatest WordPress (http://wordpress.org/download)
and upload it to the WordPress directory, overwriting all the files that
exist there. This will preserve your images and themes.
Actually it won't, at least not on a Mac. I think what happens on
Windows is that when you copy a folder such as wp-content onto an
existing folder, files inside the target folder are retained if the new
folder does not contain different versions of those files. However, on a
Mac the behavior is different. The entire target folder is completely
wiped out and replaced by the new folder. No content from the target
folder is retained under any circumstance.
I would recommend making an upgrade distribution that does not include
the wp-content folder to avoid the possibility of overwriting user files
within this folder. User and system files should be more cleanly
separated. An upgrade should not touch the user's files.
