From 512b6bb380a77233b88c84b7a712896c70281d2f Mon Sep 17 00:00:00 2001

Subject: [PATCH] gnulib/regcomp: Fix uninitialized re_token
This issue has been fixed in the latest version of gnulib, so to
maintain consistency, I've backported that change rather than doing
something different.
Fixes: CID 73828
