d a size that was not an exact
multiple of the filesystem block size.  This patch removes the check (and
failure) for reading into the last partial block (and possibly beyond) for
multiple-section files.

It worked in my testing to prevent reading beyond the end of the section;
my first patch just incremented the sect_size block count for a partial
block and continued doing the check.  But there is a commment in the source
code about reading beyond the end of the file to fill a page cache.
Failing to access beyond the section would prevent reading beyond the end
of the file.
