+### Please describe the problem.
+
+our datalad tests started to fail recently (in [this PR](https://github.com/datalad/datalad/pull/7372) is the effort to troubleshoot etc).
+
+Here is what we see with recent version using  such simple script:
+
+```
+#!/bin/bash
+
+export PS4='> '
+
+set -eu
+set -x
+
+cd "$(mktemp -d ${TMPDIR:-/tmp}/dl-XXXXXXX)"
+
+git init
+git annex init
+
+n='gl\orious'
+# touch "$n"
+git annex add --json --json-error-messages "$n"
+```
+
+that now 
+
+```
+❯ ( source /home/yoh/git-annexes/10.20230407+git63-g3d1d77a1bb.env ; bash escaped.sh )
+>> mktemp -d /home/yoh/.tmp/dl-XXXXXXX
+> cd /home/yoh/.tmp/dl-OAXQ1CE
+> git init
+Initialized empty Git repository in /home/yoh/.tmp/dl-OAXQ1CE/.git/
+> git annex init
+init  ok
+(recording state in git...)
+> n='gl\orious'
+> git annex add --json --json-error-messages 'gl\orious'
+git-annex: "gl\\orious" not found
+add: 1 failed
+```
+
+so we get `\\` instead of `\` in the output printed by git-annex
+
+<details>
+<summary>previously was all fine</summary>
