Subject: Remove assigns
X-Git-Url: https://git.dkaiser.de/?a=commitdiff_plain;h=99e8655aaf9827c7d5248c7f3d0913fcb1377cfb;p=42%2Fminishell.git

Remove assigns

I found out that there's a difference between shell variables and env
variables.
We don't have to implement shell variables, so I removed all code that
handles them.
