We were mostly ignoring them because it looks like most people's options
were longer than their positional arguments. The rest must have just
accepted the enforced wrapping.
But if you have very short options like single-letter only ones or none
at all, the positional argument wrapping is unnecessarily short.
[ChangeLog][QtCore][QCommandLineParser] Made it so the positional
argument descriptions are taken into account in the aligning of text for
helpText().
