[GNC-dev] merging failing tests

As an untrained hacker, I think the issue is whether these "bugs" are
really worth fixing at all.
I can imagine the history of the dark ages; and html was being refined,
and previously the reports were outputting plaintext or directly to
screen via X calls; the hackers decide to start outputting html via a
new upcoming framework called gtkhtml, with fancy tables, italics, font
sizes... GTKhtml comes with an over-engineered api to accept x/y
coordinates, font families, headers, pre-CSS style-sheets, paper size.
The hacker succeeds in outputting reports and uses the api calls to
render a nice report, helpfully reusing gtkhtml terminology.
Time has evolved, and gtkhtml is now obsolete. The api calls must be
changed to output html. The next hacker tries to fix the minimum code to
remove gtkhtml code, but every time a change happens, some reports break
or dataloss occurs. Therefore they fix the minimum code to move away
from gtkhtml and leave large swathes of dead old code around. "If it's
not broke, don't fix it!"
I think that completing the internal framework to successfully implement
html api code (as you have identified is incomplete) is not time well
spent. None of the reports will generate html without headers, for
instance. So, the code for testing headers should be ripped out, rather
than implemented. And code should be ripped out safely, ensuring no
tests fail, no dataloss occurs, all reports pass (including the existing
multicolumn report) and all potential users (including those not
subscribed to userlist or devel) are unaffected, and no subsequent
hacker will have to fix.
There is still a need for more hackers, so, I'm sure your efforts are
appreciated, but it's already a major headache to try understand the
previous hackers and we don't want the situation to get worse.
I think this helps? I'd love to add more features too but I'm
constraining myself too because every new code snippet, framework, or
boolean test is another headache for future maintainers.
