+> `git annex config --set <option> <value>` interprets a value with a
+> leading dash as if it were an option. Adding `--` doesn't help.
+
+I can get by the \"Invalid option\" error using `--`:
+
+```
+$ git annex config --set annex.youtube-dl-options -x
+Invalid option `-x' [...]
+
+$ git annex config --set annex.youtube-dl-options -- -x
+git-annex: annex.youtube-dl-options is not a configuration setting that can be stored in the git-annex branch
+
+$ git annex version --raw
+8.20201129
+```
+
+`annex.youtube-dl-options` isn't one of the limited set of options that `git annex config` supports though:
+
+```
+globalConfigs =
+    [ annexConfig \"autocommit\"
+    , annexConfig \"synccontent\"
+    , annexConfig \"synconlyannex\"
+    , annexConfig \"resolvemerge\"
+    , annexConfig \"largefiles\"
+    , annexConfig \"dotfiles\"
+    , annexConfig \"addunlocked\"
+    ]
+```
