[conv.rank] Remove mention of char from the first bullet

[lprv]

According to [basic.fundamental]/1, char is not a signed integer type.

This reading sounds strictly correct, but if we are taking that interpretation we should also update [basic.fundamental]p11:
" The character types, bool, the signed and unsigned integer types, and cv-qualified versions (6.8.5) thereof, are
collectively termed integral types."

I have not checked how much of the standard expects char to be an integer type --- it would be a big surprise for a lot of the standard library it if were not.

@AlisdairM , I don't understand your comment in reaction to the submission. The core wording says that "integer type" is not just a union of "signed integer type" and "unsigned integer type". There is more: char and bool fit into neither category, but are integer types. What's wrong with that?

The submitter is correct that "char" is not a signed integer type, thus does not need to be excluded when talking about "signed integer type". I'd like to see more of the surroundings to understand that "char" and "un/signed char" have the same rank, per the specification. And that should be vetted by CWG.

Never mind -- I triple read before citing my quote, but missed the very first three words "the character types,". Concern withdrawn with embarrassment.
