Absolutely... but how is /path/to/./foo/bar/ any less a "specification" of .
than of ./foo ?

Could you give me a more detailed example?

Valid point.  This is probably a case like --chmod=ugo=rwX where the default
should stand but users should realize it often isn't what they want.

/path1/, according to the usual rule that earlier source args take priority. 
This issue is in no way specific to the file-list root (you can equally well
have /usr1/./share/rsync and /usr2/./share/frobnitz collide at "share"), so it
does not justify treating the file-list root specially.

That only helps with the file-list root.  The complete solution would be to
support --exclude of implied dirs, like IIRC rsync 2.6.9 did.
