Subject: [PATCH] sniffer: Add better coverage of skip_insignificant_space()
CVE: CVE-2025-2784
Upstream-Status: Backport
[https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/435/diffs?commit_id=242a10fbb12dbdc12d254bd8fc8669a0ac055304;

Test code is not added since it uses some functions not defined in
version 2.74. These tests are not used now, so just ignore them.
