Re: running "latest" version of wget2 gives a core file.

This just in from the "latest" wget2.

wget2 wget -l 99 -r --no-parent -w 1 -A 
 causes a corefile. NOTE the extra wget. Purely an accident BUT the presence of 
a syntax error or other user screwup should NOT BE a corefile. Yes?

Here's the trace from the corefile:
