tabtab ignores ZDOTDIR

[jcf]

Hi there,

I came across tabtab in the process of installing completion of pnpm from ZSH, and noticed the automated installation ignores the ZDOTDIR environment variable. From the docs:

There are five startup files that zsh will read commands from:

$ZDOTDIR/.zshenv $ZDOTDIR/.zprofile $ZDOTDIR/.zshrc $ZDOTDIR/.zlogin $ZDOTDIR/.zlogout

If ZDOTDIR is not set, then the value of HOME is used; this is the usual case.

Writing anything to ~/.zshrc on my machine has no effect. Not sure many people make use of this feature of ZSH however, so maybe you don't need to worry about it. I just thought it worth mentioning in case you want to stick more strictly to how ZSH does its thing.

Thanks for all your work on tabtab! :bow:
