autoconf.texi contains the following:

Strictly speaking, this is not true.  The condition is that the argument
doesn't contain any macro calls, commas, nor right parentheses.

Of course, commas are mentioned a few lines below:

> [...]  Here, the argument of

Another thing which really should be emphasized is that you can omit
[ ] for readability if the parameter is very short, but you don't do it
with longer ones, even if they don't contain macro calls.

Perhaps the phrase ``simple text'' wasn't that bad.  An exact definition
could be only in parentheses after it.

I apologize that I don't have enough energy to produce a patch.
