Hello @roadrunner1776,

the problems with CB I didn't see yet. Could you please add some information on them - if they are reproducable?

The problem with output-texts containing single ' characters, I had seen already before, but I didn't regard it as serious. That is an issue, which has been existing with the EMACS delived with SW 4.x already and which has an easy workaround (see issue #24). The solution #22 just increases its impact. But is that really a reason not to implement this solution?

Yes, of course, it is a quantitative problem. Single ' characters occur much more frequently in the English language thatn single " characters. But nevertheless: the workaround is easy.

See also my discussion at the and of Issue #25

Thanks
Reinhard
