The original code assumes 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.
Also a recent change to a similar codepath by 3651e45c (wt-status:
take the alignment burden off translators, 2013-11-05) adds this
assumption:
(3) the "colon" at the end of the label string does not have to be
subject to l10n.
None of which we should assume.
Refactor the code to compute the label width for both codepaths into
a helper function, make sure label strings have the trailing colon
that can be localized, and use it when showing the section labels in
the output.

* Differences relative to Jonathan's original in $gmane/239537 are:
- labels made by wt_status_diff_status_string() have trailing
colon; the caller has been adjusted (please double check)
- a static label_width avoids repeated strlen(padding);
- unmerged status label has "at least 20 columns wide"
reinstated, at least for now, to keep the existing tests from
breaking. We may want to drop it in a separate follow-up
patch.
