After reading this very informative TeX.SE thread about spacing and punctuation, I was left wondering about an issue that didn't seem to be addressed: using
\frenchspacing together with the modified punctuation
As far as I can tell visually, using
\frenchspacing together with these commands works correctly (i.e., it seems like nothing breaks, and the extra space is suppressed as normal), but are there problems that can arise from doing so?
Moreover, when using
\frenchspacing, "should" I still use
\@. and its friends where it would ordinarily be necessary, in case someone wants to remove
\frenchspacing later? Would accommodating (hypothetical) future editors in this way be "standard", "above and beyond the call of duty", or "crazy"?
