Package: exim4 Version: 4.96-15+deb12u6 The version of exim4 installed with apt contains 20 lines that begin with a tab character followed by one or more spaces. This breaks alignment in text editors when using a tab size other than 8 and makes line by line file manipulation trickier. Replacing all tabs with eight spaces fixes this.
The Debian exim4 repo contains around a thousand lines with a tab character followed by at least one space, so I haven't been able to track down the source of this. I believe these tabs are also all standing in for eight spaces. Ben Raven
