I'm not a member of this list but someone forwarded the cited note to me,
so I hope folks don't mind a comment and I apologize if I miss any replies.
The Question is: should the size of the
parentheses/brackets/braces be adjusted in case of intervals or
functions. *Regardless* inline or display.
AFAIR in Jim Hefferons algebra book, the size of the interval
parentheses is *not* adjusted. One reason, may be, is not to confuse
the interval parenteses with the "normal" multiply parenthes. Who
knows. Math typography is a (undocumented) mystery.
I do it just as you've said, to prevent confusion (although I can't
remember using it in my LA). I'd think that the interval from 2/3 to
7 shown as:
| 3 .. 7 )
would be bad, and a matching large one would also be bad. To my mind,
the interval is set in regular type (even in display), just as sometimes
I might have "where $x>p$" at the end of a display line.
But I'm no authority. And my edition of Swanson's _Mathematics Into Type_
doesn't seem to say. In that case, I usually look at a couple of books
whose typography looks good to me and try to mimic what I see there. Did
you look through a half-dozen reputable books (not mine!)? The AMS
materials seem to me to ba authoritative, and Springer, Elsevier, etc.
