An error was thrown (`bash: [: =: unary operator expected`) when using the __git_ps1_colorize_gitstring function outside of the one place it's called (line 512), because the "detached" variable was not quoted, and was unset.

* Fix bad function definitions in Debian plugin

There appears to be a definition issue for some functions/aliases which
result in the following errors when sourcing .zshrc:

```
/home/username/.oh-my-zsh/plugins/debian/debian.plugin.zsh:75: defining function based on alias `abd'
/home/username/.oh-my-zsh/plugins/debian/debian.plugin.zsh:75: parse error near `()'

- Add mercurial support to af-magic, so now the vcs prompt will show up in either a git or hg repository
