Summary: minor bug in new {expand}-parsing

Initial Comment:
there are a few cases, where {expand}  *without* trailer is 
misinterpreted to expand to nothing:

in interactive tclsh8.5 shell:
% list {expand}
% list {expand};
% if 1 {list {expand};}
%
(all return the empty string, instead of the string "expand")

However
% if 1 {list {expand}}
expand
%
works correctly.

It looks like the code that checks the next character after 
the {expand} deals with too few cases.

another failing case (also in interactive shell):
% list {expand}      whatever else
whatever else
%
(since \-newline-anywhitespace should be treated as one single
whitespace, the {expand}-semantics shouldn't trigger.

This might be more difficult to fix  than the previous cases :-(
