Wrong error message when wrong multicharacter short option is passed

[ocervell]

Sometime it is usefull to have not only single char short option like -d but something like -dbg.

They are already working as-is (even though not documented), but when passing a wrong option such as -dbgwrong, the error displays: No such option: -d instead of No such option: -dbg.

@davidism I have only seen single character short options. Do we intentionally support multi character short options?

Hi @davidism,
any updates here ? It seems we do accept multi-char short options, so we should have the proper error message when they are not found.

[davidism]

This is the correct error message. Short options can be stacked, -dbg is equivalent to -d -b -g, so the first unregistered option raises an error.

Just reopening for docs addition.

Add docs section in options section with:

• Title: combining short options
• the short option combining behavior explanation and example
• note about multi character short options not being supported
