Good.

I think this is fine though the list looks pretty arbitrary.
(for example, why are #\{, #\}, #\[, #\], #\(, and #\) not
encoded?)  I think it's fine that if a library name does not
map to a file name accepted by some who-knows-what file system
or operating system, too bad, pick a different name or curse
the system.  If you have reasons for picking these chars for
encoding and not others, you probably need to say why, in a
footnote or endnote perhaps.

Fine.

Fine.

Fine.

This sounds fine by me.  I'd like to know Will's opinion.

The "must" should be "may".  I can imagine an implementation that does
not wanting to provide implementation-specific files.

I don't know what you're referring to exactly but I don't think you
should say much (or anything) about what goes in implementation-specific
files.

SCHEME_LIBRARY_PATH, yes. :-)

Yes.

I believe these changes will make a much better SRFI.  Thanks for all
the effort.
