I know for sure Windows native UI supports dialogs without a default
button, and Motif also should support this as well. I will in fact be
surprised if GUIs always force the programmer to specify a default
button, as there should be a choice not to have one (especially when
there is a complex interface).
In my case, I was trying to set no default button when I know there is
some important information to read, but the user might routinely press
<Space> or <Enter> to get rid off it. If the dialog doesn't get hidden,
the user will more likely read it. Right now I resorted to doing an
echohl with WarningMsg followed by an input(), but this introduces a
drastic difference from the routine case where the user still sees a
dialog.
