Thanks for spotting this.  I'll add it next to the -xdev option.  The same problem is in the find(1) man page.  Only info documentation mentions the -xautofs option now.

Hmm, the find(1) man page on my F-13 system (findutils-4.4.2-6.fc13.x86_64) does have it:

       -xautofs
              Don’t descend directories on autofs filesystems.

You're right, my mistake.  I'll just add the entry to --help.
