### Please describe the problem.
I did manage to reach the rabbit hole bottom in the troubleshooting of my unique inability to use argcomplete for shell completion in datalad: [datalad issue](https://github.com/datalad/datalad/issues/4538) [argcomplete issue](https://github.com/kislyuk/argcomplete/issues/303)
And the bottom looked liked:
```
$> IFS=$'\013' /usr/lib/git-annex.linux/git-annex version
[1] 1040489 segmentation fault (core dumped) IFS=$'\013' /usr/lib/git-annex.linux/git-annex version
$> IFS=$'\013' /usr/lib/git-annex.linux/git version
[1] 1040532 segmentation fault (core dumped) IFS=$'\013' /usr/lib/git-annex.linux/git version
```
whenever stock git is ok
```
$> IFS=$'\013' /usr/bin/git version
git version 2.27.0
```
most likely it is just a matter of sanitizing this variable in `runshell` or alike.
