Re: AC_DEFINE_UNQUOTED doc update

[Stepan Kasal]

Hello,

autoconf.texi contains the following:

>  [...]  You may safely leave out the quotes when the

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.
