Subject: Don't call external tools, use variable modifiers
X-Git-Url: https://arthur.barton.de/cgi-bin/gitweb.cgi?p=ax-zsh.git;a=commitdiff_plain;h=062ed4a6b1dbb6bb7cd92d05cc4e7155086f96f7

Don't call external tools, use variable modifiers

Not calling external tools like basename(1) and readlink(1) but ZSH
variable modifiers greatly enhances startup performance, especially on
slow machines.
