True :), I just copied the same test from the w3m test.
Apparently in all the configure.ac source there is ! -z instead of -n.
Do we want to replace all these occurrences? Do you have an idea why !
-z was used instead of -n? Is there any shell where test -n does not
work?
I'm not sure, but if I remember correct, there was a difference in
behavior if a variable does not exist or if it is empty.
But I couldn't find anything about this.
