Lucas has run an archive rebuild and he didn't report any package failing to build. Please note this warning comes from an erroneous search pattern, and is that pattern that should be fixed. In this case, grep has fixed its behaviour. Anyway, I am planing to apply the attached patch to temporarily disable the warning by default. Cheers, -- Santiago
Description: Temporarily disable the stray \ warnings. While the related
patters are wrong, these warnings are causing trouble in Debian package
builds and autopkgtests.
This patch should be removed after coordination with the rest of the project
to remove the erroneous patterns.
Setting the DEBIAN_GREP_ENABLE_STRAY_BACKSLASH_WARN environement variable
restores the upstream beahviour, enabling the warning.
