I was going to suggest some wording like:
When set to "all", include options considered unsafe such as --force
in the completion.
However per your cover letter it's not just used for that:
10 --force
4 --rerere-autoupdate
1 --unsafe-paths
1 --thin
1 --overwrite-ignore
1 --open-files-in-pager
1 --null
1 --ext-grep
1 --exit-code
1 --auto
I wonder if we shouldn't just make this only about --force, I don't see
why "git grep --o<TAB>" should only show --or but not
--open-files-in-pager, and e.g. "git grep --<TAB>" is already verbose so
we're not saving much by excluding those.
Then this could just become:
GIT_COMPLETION_SHOWUNSAFEOPTIONS=1
Or other similar boolean variable, for consistency with all the "*SHOW*
variables already in git-completion.bash.
