Fix command completion for zsh

[terabyte128]

zsh only reads the first line of a file when searching for #compdef lines. The completion script added a comment above this line and caused zsh autocomplete to fail.

When compinit is run, it searches all such files accessible via fpath/FPATH and reads the first line of each of them. This line should contain one of the tags described below. Files whose first line does not start with one of these tags are not considered to be part of the completion system and will not be treated specially.
