Latest --files-from patch

[Wayne Davison]

If anyone is trying out my --files-from patch, please grab a new version
from here:

    http://www.clari.net/~wayne/rsync-files-from.patch

I fixed a potential bug in the pathname-reading code when pulling files.
This version also sanitizes all read pathnames, as discussed elsewhere.

Remember that this patch is still young, so use it for testing only.
