All makes sense, and as long as nobody uses strbuf_add*() on
line->buf directly, it shouldn't be too hard to extend these
to support graph drawn characters outside ASCII in the future
after this series settles.

Nice reduction of noise, as the proposed log message promises.

I just noticed it but does this have to be extern? Nobody outside
graph.[ch] seems to have any reference to it. That might mean that
it may be easier than we thought earlier to change the second
parameter of this to "struct graph_line *", instead of us wrapping
an incoming strbuf (which external callers are aware of, as opposed
to graph_line which we prefer not to expose to outsiders). Whether
we change the second parameter or not, the first clean-up may be to
turn this function into a file-scope static, perhaps?
All the changes are very pleasing to see. Thanks.
