Setting escape-time to 0 makes bindings using alt/meta not always work

[sersorrel]

I have the following in my .tmux.conf to switch windows with alt-h and alt-l:

bind -n M-h previous-window                                                      
bind -n M-l next-window

and sometimes with escape-time set to 0 by tmux-sensible, then ^[h or ^[l will be echoed in the terminal rather than switching windows. Setting escape-time to 10 seems to fix the problem without adding any noticeable delays when pressing esc elsewhere (for example in Vim) – could this be made the default in tmux-sensible?

Supporting this issue also due to this StackOverflow answer.

TL;DR: escape-time should never be set to 0, but rather something small like a value between 5 and 100. Otherwise it can cause weird bugs where escape sequences fragmented over multiple packets are not recognized properly.
