This is often caused by capturing output from a pseudo-terminal (pty)
like script(1) does. Unix text files conventionally use \n line endings,
and programs conventionally output \n, but Unix terminals must translate
this into \r\n, otherwise the output will show a "staircase" effect
where the cursor doesn't return to column 0 on new lines.
In the case of sbuild logs, all the \r usually come from apt
installing the build-dependencies, which works by capturing text from
