zsh tries to "exec" environment assignments

[Raúl Núñez de Arenas Coronado]

Binary package hint: command-not-found

From a clean promt, do the following:

$ FOO=BAR false
FOO=BAR: command not found

The same applies for any command that returns non-zero status if any environment assignment exists, the first assignment is run.

The culprit is /etc/zsh_command_not_found. I haven't had the time to read the code and check for the particular piece which is causing the problem, so I cannot give a patch.

Another example:

% (( 0 ))
((: command not found

This is a common idiom in zsh (to follow with an && or ||), so pretty important that it works.

Fix released long ago (for the original issue and the one mentioned by mde) by using zsh's command_not_found_handler() instead of the hand written cnf_precmd()/cnf_preexec() magic in /etc/zsh_command_not_found.
