Hmph, I am talking about

where the callers already supply _("Untracked files") and _("Ignored files")
without trailing colon in "what" when calling wt_longstatus_print_other(),
which is a direct caller that passes "what" to this function.

So, no, I am replacing

	printf("%s:", _("Untracked files"))

with

	printf(_("%s:"), _("Untracked files"))

and no other changes are required.  When translating "%s:", French
translation can insert nbsp before the colon to make it "%s :",
right to left languages may want to put their equivalent to colon
that comes after a heading on the left side of the "%s", etc.

With "Untracked files" and "Ignored files", we indicate certain
concepts and interpolate it in _("%s:"), i.e. a version localized to
adjust to the presentation convention of "label followed by a
separating colon".  Unless your language requires to translate
"Untracked files" differently when it is used as a "label" to be
followed by a separating colon and when it appears elsewhere in a
sentence, I am not sure how it helps to mark "Untracked files" as
appearing as a header label.

Besides, in the existing code, the form that is equivalent to

	printf("%s:", _("Untracked files"))

is being used, and where that "Untracked files" appear is two level
function calls away from the actual "%s:" (i.e. "label and
separator").  Aren't translators translating this string without
extra context?

The way the function wt_longstatus_print_other() uses "what" and
"how" looks quite clear.  What kind of paths are being reported (are
they ignored files?  untracked files?  something else?) and how the
user can rectify the situation if they want these paths included in
the tracked set of paths.  I am afraid renaming to "heading" makes
it even less clear than leaving it to "what".  A word that indicates
that it refers to "category of paths" more clearly may make a good
replacement, but perhaps I am not understanding where exactly your
"this hides the information" comes from and makes you worry about
it.  Besides, would translators work off of .po and .pot files, not
the C-source?  Do they even have ready access to the variable names
to help them infer how the strings are used to begin with?

If translators truly benefit from knowing that the string "Untracked
files" is used as a heading, we could use /* TRANSLATORS: insn */
comment to help them.  Since I seem not to get where your concern
comes from, I cannot tell if it would help.

More info needed, I guess?
