I think we have something like a length count for file names in index
and/or tree.  We could just put the (sorted) attributes after a NUL
byte in the file name and include them in the count.  It would also
make those artificially longer file names work more or less when
sorting them for deltification.

However, this requires implementing _policies_: it must be possible to
specify per repository exactly what will and what won't get tracked,
or one will get conflicts that are not necessary or appropriate.
