Add "lucky" command

Inspired by the Google Search "I'm feeling lucky" button.

This is silly, but fun. It silently privileges the first match. For example, srfi lucky record shows SRFI 9.

Merged and pushed, but I refactored it to use srfi-search first, and fixed an already existing warning about multiple definitions of with-output-to-string.

Yeah. It's half easter egg, half feature. But surprisingly often useful - as was the original, I guess. I now use it more often than the search command. If you can think of a better criterion than picking the earliest matching SRFI, please change it.

We could perhaps also add a command that browses a SRFI with the given library name.

Thanks for the fixes - good catches both.

How about just displaying all the matches, then jumping to the first one?

srfi search foo shows all the matches. What do you mean by jumping in this context?

then send the browser to the first one.

Right. Sounds reasonable to me.
