Feed all zsh history into fzf (not only most recent)

[wellle]

When I execute history in Zsh I see only the 16 most recent commands. Fuzzy finding on them doesn't make much sense. Adding -$HISTSIZE shows all commands from the history that are saved.

Also adding -n removes the command index, so the sed command can be removed.

Hey, thanks for the patch! I didn't know that history command of zsh truncates the list by default.
But could you restore the numeric index part?
I find it quite useful when the list is filled with many similar items.

[wellle]

Done.

[junegunn]

Thank you.

@wellle I've just realized that this change doesn't work on oh-my-zsh,
where history is an alias to fc -l 1.
Although I'm not particularly fond of oh-my-zsh, it has such a large user base,
so I've made a slight adjustment to the command.

[wellle]

Oh that's an important point! Looking at it again, instead of 'history' -$HISTSIZE we could also use one of these:

1. 'history' 1
2. fc -l 1

Both should work and seem simpler than what we have right now. Let me know if you want me to implement either of these.

[junegunn]

Okay, looks good to me. I'm fine with either one. Feel free to open another PR. Thanks.

FWIW, you could use 'command history' to skip any aliases.

@blueyed Thanks. There was a recent pull request which applied that method.
