The plugin is a copy of the completion script shipped by symfony/console. It has not been updated since it was added, and two fixes made upstream since then are missing. The completion request was assembled as a string from the raw words of the command line, then passed to "eval". Any command substitution present in a word was therefore executed by the completion, before the user validated the line. The request is now run as an array of arguments, without being read again by the shell, and "_describe" is called directly instead of through "eval". The alias of the command is resolved explicitly, since that was the only useful effect of the "eval". The request also runs with SHELL_VERBOSITY=0, so that completion keeps working for users who exported SHELL_VERBOSITY=-1. Ported from symfony/symfony#65818 and symfony/symfony#63859.
