18dbpagesize_binpower.dpatch by  <hesso@pool.math.tu-berlin.de>


Make sure that the pagesize passed to db__set_pagesize() is a power of two.

nvi stores the content of files in BDB database structures. When initiating a
file, it picks a page size for the database to fit the file within 15 pages,
with a minimal page size of 1K and maximal of 10K.

In vanilla nvi, this size is calculated as a multiple of 1024. Modern versions
of BDB, however, require the page size of a database to be a power of two, which
this patch addresses, ridding us of the following message:

  BDB0511 page sizes must be a power-of-2
