+======Synopsis======
+$__shiftbrace__(<lval>)
+======Returns:======
+If the value of the named variable begins with a braced expression
+(surrounded by curly braces), the expression will be removed from that
+variable and the inside of the expression will be returned.
+If the value of the named variable does not begin with a braced expression,
+then the variable is not changed and the empty value is returned.
+Extra spaces may be important!  This may change in the future.
+======Examples:======
+<file>
+/assign qwer {asdf zxcv} {zxcv asdf qwer} one two
+/eval echo $shiftbrace(qwer)  =>  asdf zxcv
+/eval echo $shiftbrace(qwer)  =>  zxcv asdf qwer
+/eval echo $shiftbrace(qwer)  =>  (the empty string)
