`--hints:off` doesn't work (doesn't override ~/.config/nim.cfg)

[timotheecour]

~/.config/nim.cfg:
hint[source]=on

test.nim:
1+1

 nim compile --run --verbosity=0 --hints=off '--hint[source]=off' --path=./ /tmp/z01.nim
/private/tmp/z01.nim(1, 2) Error: expression '2' is of type 'int literal(2)' and has to be discarded

nim compile --run --verbosity=0 --hints=off --path=./ /tmp/z01.nim
/private/tmp/z01.nim(1, 2) Error: expression '2' is of type 'int literal(2)' and has to be discarded

--hints:off is supposed to turn all hints off (from docs); however as shown above, --hints=off '--hint[source]=off' was needed to undo the effect of ~/.config/nim.cfg

perhaps what's going on is that currently, --hints=off is applied BEFORE reading ~/.config/nim.cfg (instead of after) ?

NOTE: this seems to be the root cause of inim-repl/INim#16

( I had hint[source]=on in my ~/.config/nim.cfg, and --hints=off should've cancelled that hint, but didn't)
