tmux prompt corruption with git_prompt_info

[jhartikainen]

Inside a tmux session, if you use zsh with oh-my-zsh themes that use the git_prompt_info, it causes corruption of the prompt/line when in a Git repository directory.

Steps:

1. Enable theme with git_prompt_info (I use flazz)
2. Go into a directory with .git
3. You should notice the prompt contains some extra spaces, and typing causes the characters to appear in the space. You should additionally notice that if you try editing a line from history, it will be shifted a few spaces forwards making it hard to edit it correctly.

Expected:

No issue in step 3

Possible cause:

Users on the zsh IRC channel said it was probably caused by the output of the git_prompt_info command, and not caused by tmux itself.

This is caused by broken unicode support in tmux, not by OMZ. Try a theme that does
not have pictographs for status indicators.

Are you using the latest tmux? I believe the latest version fixed quite a few unicode
bugs.

I have the latest tmux version (1.5 on Archlinux 64), and I'm not using OMZ, and I see an annoying space in tmux only (with or without a .git in the directory)
My .zshrc https://github.com/kooothor/Dotfiles/blob/master/.zshrc

I think the bug comes from tmux itself...

To solve the bug, start tmux with the -u flag (to get unicode working).
