So, it looks likethe following is closer to working for me in a simple
test harness, but not in my full-blown work:
(or similar with string.fullstrip).
However, it fails when the buffer starts with an unescaped left square
bracket. That is probably why the \relax is inserted, and I can see that
it is not a simple job to handle this. So, I will accept that I must
either append  or get rid of the open layout for these cases.
I suspect that the issue in the larger project has to do with quoting
for the RE ("^\\relax") since compilation fails with:
%% \stopAttribution ...getcontent("Attribution"),"^\\
Any pointers on such quoting would be appreciated.
