Issue changing tabs in iTerm

[karptonite]

When changing tabs in iTerm with the hot keys, I see escape sequences printed into the vim window. ^]]0 and ^]]I, I believe. Since I'm currently using vitality just to fix the cursor, I just changed enable_focus_reporting and disable_focus_reporting to "" in a fork.

I'm using xterm-256color for my terminal, if that makes a difference. I saw that there was a TODO in the code, "Look into how this works with iTerm tabs. Seems a bit wonky."--I'm guessing this is related?

Related to #19 you can disable the FocusGained and FocusLost features by using:

let g:vitality_fix_focus = 0

Note that you have to do this before sourcing the plugin.

I believe I've fixed the underlying wonkiness in iTerm2, see this iTerm2 PR and issue. Feel free to see if the fix (which requires compiling iTerm2) works for you.
