Improve error when help fails to find a browser

Browse source 
Previously, this message told the user to "set $BROWSER and try again". However,
when I first saw this error, I didn't know how I can set `BROWSER` in fish. Moreover,
I often see this error in situations when no browser will work. For instance, I might be
using fish over ssh, and I might either not know whether that system has a text-mode
browser installed or not want to use it.

A further improvement would be to report this message if a browser fails to start.
