This is an inconsistency with many of the symbol commands. For
example, \textglotstop for the glottal stop character (in TIPA) needs
to be followed by a space or {}, but \textipa{?} does not, since it
has brackets. Accented characters, on the other hand, work without a
space after them: \'a gives you รก... Why eszett and accented a should
behave differently is not clear to me, but they do.
The reason is that \'a is really \'{a} and is interpreted as such.
Similarly \"o, etc. LaTeX lets you be sloppy here, since there's no
danger of misinterpretation, whereas \ssend could be a command in its
own right.
