Lighttpd

Hi,

I found out that giving -f more than once can cause problems.

lighttpd -f lighttpd.conf -f lighttpd.conf

It was the same .conf file btw (which was my accident, I just found out that lighttpd hates this)

Lighttpd then will say:

lighttpd: configfile.c:1101: config_read: Assertion `context.all_configs->used == 0' failed.
Aborted

And it will abort.

When I first had this problem, it was not obvious to me why it happened (I used an alias actually and then just appended -f again to this alias, which used -f already).

The error message: "Assertion failed" was not useful to me.

Proposal:

Make this specific error message more useful in case a user uses the -f option twice (or more than once).

Suggestion for error message, in case of abort-like problems:

"You seem to be using the -f option more than once."
"Please review your configuration files as they may contradict each other."

And then a listing which specific configuration option is in conflict perhaps - that would be most helpful.
