Re: --init-file option

Yes, I could do something similar as what zshi does, but that seems like a suboptimal solution, because it would require a duplication (and indefinite maintenance) of the startup file processing logic in an independent codebase. As the logic is not trivial and has some potential pitfalls as well, it seems to me that implementing the option within Zsh would be the most sound (and perhaps simplest) solution from an engineering and long-term maintenance perspective.

zshi essentially automates this process. It also takes some care of
restoring `ZDOTDIR` before sourcing the real user rc files and
checking `[[ -o rcs ]]` afterwards. There is still one thing that
breaks when using zshi (or doing the same thing manually): global rc
files see the wrong `ZDOTDIR`.
