### ImageMagick version

7.1.1.15

### Operating system

Linux

### Operating system, version and so on

Gentoo Linux

### Description

I lost a bunch of files because I had a typo in my shellscript and imagemagick returned a success exit code despite not finding the files.

### Steps to Reproduce

Way to replicate:

`convert nonexistingfile.png && echo success`

Running this wrong command prints a help messages and then exits with success code echoing success. Instead it should return a non-zero exit code!
