Replace spaces by tabs for consistency. The rest of the codebase uses

Removed trailing tabs in all codebase.

Improve error messages generated by `errx()`, `warnx()` and similar.
Set `progname` to a static string with the name of the program so that
the path of the binary isn't included in error messages.
