Documentation/process/coding-style:

Choose label names which say what the goto does or why the goto exists.  An
example of a good name could be ``out_free_buffer:`` if the goto frees ``buffer``.
Avoid using GW-BASIC names like ``err1:`` and ``err2:``, as you would have to
renumber them if you ever add or remove exit paths, and they make correctness
difficult to verify anyway.
