Not wrong in my view, but incomplete and using undocumented escape
sequences yields unspecified behavior.  The intent was to mimic fstab(5)
behavior, and IIRC I noticed at the time that \xHH was supported
although not documented either.  Either way, better stick to documented
escape sequences in both files.
