-? fails when using ZSH

[KristofKoch]

Description of the problem
When using the ZSH shell the -? argument doesn't work. Generally not a problem as no argument has the same behavior. It becomes a problem at least with begin and end where no argument is required for proper operation. As ZSH is the new default shell for MacOS this might become more of an issue.

We have the same issue with csh (#3916), but I think nothing we can do on the GMT side.

For zsh, ohmyzsh/ohmyzsh#31 provides two workarounds.

1. Add noglob before commands, i.e., noglob gmt coast -?
2. Add unsetopt nomatch in .zshrc

I'm closing the issue because GMT can do nothing here. Feel free to reopen the issue if you think more discussions are needed.
