The 'default' argument to the highlight command is only used to determine
whether the new
attributes/link can override the already existing attributes/link and the
'default' setting is not
stored with the highlight group in the internal Vim structures. So the
hlget() function cannot
return this as it is not present in the internal Vim highlight group
structures.
For example, you can run the following commands:
:highlight hlg1 ctermfg=2
:highlight default hlg2 ctermfg=2
:highlight hlg1
hlg1 xxx ctermfg=2
:highlight hlg2
hlg2 xxx ctermfg=2
As you can see from the above output, both hlg1 and hlg2 have similar
output and the
"default" setting is missing for hlg2.
