Yes, that is right.  This file is a bit of a crazy thing, if there is
a better way to achieve this, I would be glad to know.
Use a data structure.

In the simplest case (when lookup time is not critical), just use a
linear structure, an alist: For each VOL, define an alist with elements
(pagelimit . filename) with `defconst'.  To implement
`mandoku-cbeta-vol-page-to-file', find the first entry whose car is not
smaller than the given page in a loop.  Return the cdr of the found
cons.
Well, yes. But I expect the timing then to be slower (although I did not really test this), because I would have to go sequentially through the alist, so I went with this inelegant method, which at least responses fast, even without bytecompiling.
