git bash completion modifies COMP_WORDBREAKS breaking other autocompletion

Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue) I used bash autocompletion. So: git <tab>

What did you expect to happen? (Expected behavior) The bash environment variable ${COMP_WORDBREAKS} remains unmodified.

What happened instead? (Actual behavior) COMP_WORDBREAKS is modified. Specifically, a colon is appended.

What's different between what you expected and what actually happened? COMP_WORDBREAKS being modified.

Anything else you want to add:
This breaks auto-completion of programs that rely on completing 
arguments that
include colons. For example, autocompleting arguments like: "file://abc" 
- hitting
tab gives something like "file:file://abc". As far as I'm aware, modifying
COMP_WORDBREAKS is no longer considered good practice.

Doing some research, I see the following patch, which I'd be in favor of using: https://patchwork.kernel.org/project/git/patch/20201104174716.783348-6-felipe.contreras@gmail.com/

Not sure if this will just get lost in the noise, but I figured I'd send this at least as a 'bump' towards this issue.
