### ImageMagick version

7.1.1-19

### Operating system

Linux

### Operating system, version and so on

openSUSE Tumbleweed 20231008

### Description

When calling convert 7.1.1-19 with "-help", it gives an error at the end:

with an image format name and a colon (i.e. ps:image) or specify the
image type as the filename suffix (i.e. image.ps). Specify 'file' as
'-' for standard input or output.
convert: missing required argument @ error/convert.c/ConvertImageCommand/562.
It exits with rc 1.

In my opinion it should give back the usage, nothing more. On 7.1.0-9 there is no error message and it exists with 0.

### Steps to Reproduce

ds@morbo convert -help >/dev/null
convert: missing required argument  @ error/convert.c/ConvertImageCommand/562.
ds@morbo echo $?
1
