Other posters have also asserted this.  I don't see it.

K&R2, section A7.19, says "Constant expressions may not contain ... comma
operators."  Case expressions are constant expressions.  Therefore the
overloading of commas in a "case list" construction is not ambiguous,
although it might confuse humans.

Other posters have also pointed out that ranges of characters such as
'A' .. 'Z' are inherently unportable w/r/t character set.  This is true,
but ranges of enums remain safe and useful, since enums are guaranteed to
be assigned values left-to-right increasing by 1.  A large enum declaration
may be listed in order of logical groups, and then a range could be used to
test whether or not a particular enum variable had a range within the group.
