Fish uses htmlview to display its help. So htmlview should be a dependency

I was about to come and report this; I just discovered fish. A transcript of my first session: % /usr/bin/fish Welcome to fish, the friendly interactive shell Type help for instructions on how to use fish klempner@kenmore ~> ls (snip) klempner@kenmore ~> help fish: Unknown command 'htmlview' /usr/share/fish/functions/help.fish (line 12): htmlview file:///usr/share/doc/fish-1.21.3/index.html & ^ in function 'help', called on standard input, klempner@kenmore ~> at which point I came here to report this bug, if it hadn't already been reported.
Fixed, thanks!
