:buffer # works.
:buffer $ does not, but it may be good to make it work.
Reverse (:#buffer and :$buffer) should not work. VimL syntax is already far
too complicated for the purpose it is used. Handling # or $ specially for a
:buffer command will make it even more complicated.
Note: everything that goes before the command is range. Range is
transformed into line numbers before command is processed. Thus it does not
receive information about an exact string that expanded into specific line
number.
It may be possible to workaround without complicating commands parsing by
saving information about atoms though, but I would not welcome a hack that
leaks information from one level of processing to the other.
