And it is even worse that value_regex uses ERE, not BRE, which means even an otherwise innocuous letter like '+' cannot be used without quoting. > You can demo it for yourself like so: > > git init repro+for+maintenance > git maintenance register > git maintenance unregister > echo $? # returns '5' > git config --list --global > > I see two paths forward: > 0.

If there's a reason why it's not simpler to do it that way, it's > my fault for missing the review :) My short-to-mid-term preference is to do #1 to allow a value to be spelled literally (i.e. remove entry with _this_ value, and add this one instead), and optionally do #2 as an optimization that is not essential. I do not offhand know how you can make #2 alone fly without doing some form of #1, as I think the same value_regex that ought to be ERE to specify entries to be replaced needs to be used under the cover even if you use "config API" anyway. Thanks.
