This prevents it from malfunctioning when `setopt prompt_subst` is off.

Move the DISABLE_AUTO_TITLE check from title() to the preX hook
functions that call it, to allow the title() function to be used
directly by user or other callers.

contaminating script/function output

In older version of zsh, `add-zsh-hook` is not available, causing issues like:

```
/Users/hugo/.oh-my-zsh/lib/termsupport.zsh:32: add-zsh-hook: function definition file not found
/Users/hugo/.oh-my-zsh/lib/termsupport.zsh:33: add-zsh-hook: function definition file not found
```

See https://github.com/robbyrussell/oh-my-zsh/issues/748. This patch pulls in the changes suggested in https://github.com/robbyrussell/oh-my-zsh/issues/748#issuecomment-37862691 by @mcornella and I have tested it on RHEL 5.

Fixes formatting on some rare cases when a percent ends up
in the $CMD variable, like these below:

- When assigning a variable, $CMD ends up with the second parameter;
in this case, $CMD will contain '+%s%N', messing with the syntax:

 $ a=`date +%s%N`

- A function (or command in general) that contains a percent symbol:

 $ to\%() { echo $(( $1 * 100 / $3))\% } # $CMD=to%()
 $ to% 2 of 10 # $CMD=to%

Fixes #2182

Fixes issue #1884

Revert "Fixed Mac OS X Terminal.app related issue with extra newlines being printed out sometimes"

This reverts commit 8f89d4d5.

Before this patch, commands containing %-signs set the title wrong
(urxvt and xterm) [1] and produce strange output in urxvt [2].

test for bug 1:
> sleep 10 && echo %
sets title to "sleep 10 && echo %<<"
> sleep 10 && echo %f
doesn't change the title at all

test for bug 2 (only urxvt):
> echo %f
39m%f
^^^^^----- output

This is needed to play nice with plugins that need various hooks.

Fix by derekjw. closes #52.

Closes #45 #57 #58 #86.

Was causing iTerm title to disappear entirely..

This reverts commit d4ea399b.

doesn't support tabs titles.

Term window title and tab title are now skinable
Tab title can be different from window title (when supported by term)
Default theme is optimized of usuability (no %u@%m: $~ in a 10 char tab)
Cleanup code duplication and add comment for supported terms
On osX it works great on iterm, and is decent once you tweak Terminal pref
Tested under GNU screen, iTerm and Apple Terminal, need to be tested on linux
TODO implement Konsole support (via dbus)

Revert "Added my prompt theme, with a tweak to the core oh-my-zsh to support it. My git_prompt_info function not only reports the branch and dirty status, but also whether or not the branch is ahead or behind of the remote, or both. It also switches the prompt colour from green to red if the previous command exited with a non-zero value (i.e. failed)."

This reverts commit 14a1ce80.
