Hi list and Bram.
I got a report that synIDattr() returns "-1" (string) for undefined ctermfg.
:echo string(synIDattr(synIDtrans(hlID('Visual')), 'fg', 'cterm'))
'-1'
Is this an intented behavior?
And I wrote an attached patch to make it return empty string "" for this case.
I don't know it should be fixed or not, so please check it.
Best.
