Allow the argument given to lstatfs() to be a file -- in which case,
we'll call fstatfs(2) instead of statfs(2).

That is, for most people these too lines will print the
same things:

(print (statfs '/var))
(print (statfs (fopen '/var/log/messages)))

Add siod.scm to the list of those with MS-DOS line-endings.

There are no packages for 3.6.2, so not updating PORTREVISION yet...
