commit 5221837e62641958f237e7fb5dee999cbfc850c9
Author: Theodore Ts'o <tytso@mit.edu>
Date:   Sun Dec 16 15:41:15 2007 -0500

    fsck: '#' is only a comment character at the beginning of an fstab line
    
    Fuse and ssh fstab lines such as:
    
      wdfs#https://dav.hoster.com/foo/bar /mnt/hoster fuse user,noauto 0 0
    
    will cause fsck to issue warnings about invalid fstab lines, because
    fsck was previously treating '#' as a comment when it appeared
    anywhere in an fstab line, not just at the beginning of the line.
