subcommands are not parsed when usageHelp = true and required param is missing

[mkavanagh]

I'm implementing a CLI where the top-level command has two params (a required = true param and a usageHelp = true param), plus a number of subcommands

When the command is parsed with the required param missing and the usageHelp param supplied, I can check isUsageHelpRequested and print the usage for the top level command

When a subcommand is included I have to either:

• include the required param as well in order to get the subcommand parsed without error (so that I can print the usage for it), or
• annotate the help param with help = true as well as usageHelp = true in order to pass the check at https://github.com/remkop/picocli/blob/master/src/main/java/picocli/CommandLine.java#L2094 and still be able to tell whether help was requested (I can't see any way to tell if a param with just help = true was parsed)

Thank you for reporting this!

I've fixed the issue in master. I will roll a release for this as soon as possible, hopefully within 24 hours.
