It looks like the original code is assuming that

 (1) the number of bytes written is the width of a string, so they can
     line up

 (2) the "how" string is always <= 19 bytes

Both assumptions are problematic.

Perhaps the value '20' should be dynamic (e.g.,

        min(20,
            1 + max(utf8_strwidth(all 'how' strings
                                  in the current UI language)))

) to allow the text to always line up?  Ever since 3651e45c
(wt-status: take the alignment burden off translators, 2013-11-05),
wt_status_print_change_data() picks its width dynamically for the same
reason.  So, something like the following (untested)?

This includes the colon in the translated string, to make it easier to
remember to keep the non-breaking space before it.
