The current code reads the config and command-line options
into a separate "colopts" variable, and then copies the
contents of that variable into the "struct wt_status". We
can eliminate the extra variable and copy just write
straight into the wt_status struct.

This simplifies the "status" code a little bit.
Unfortunately, it makes the "commit" code one line more
complex; a side effect of the separate variable was that
"commit" did not copy the colopts variable, so any
column.status configuration had no effect.

The result still ends up cleaner, though. In the previous
version, it was unclear whether commit simply forgot to copy
the colopt variable, or whether it was intentional. Now it
explicitly turns off column options. Furthermore, if commit
later learns to respect column.status, this will make the
end result simpler. I punted on just adding that feature
now, because it was sufficiently non-obvious that it should
not go into a refactoring patch.

There is no reason not to, as the user has to explicitly ask
for it, so we are not breaking compatibility by doing so. We
can do this simply by moving the "show_branch" flag into
the wt_status struct. As a bonus, this saves us from passing
it explicitly, simplifying the code.

When the "-z" option is given to status, we are supposed to
NUL-terminate each record. However, the "-b" code to show
the tracking branch did not respect this, and always ended
with a newline.

This option is passed separately to the wt_status printing
functions, whereas every other formatting option is
contained in the wt_status struct itself. Let's do the same
here, so we can avoid passing it around through the call
stack.
Signed-off-by: NJeff King <peff@peff.net>

The options are declared as a static global, but really they
need only be accessible from cmd_commit.  Additionally,
declare the "struct wt_status" in cmd_commit and cmd_status
as static at the top of each function; this will let the
options lists reference them directly, which will facilitate
further cleanups.

In the case the pointer could be NULL, the function that gave the caller
the NULL pointer would already have issued an error message, so simply
returning early with an error status without issuing a new message is
sufficient.  The same for parse_commit() that will show necessary error
message when the argument is not NULL, and will return error silently
when the argument is NULL.
