Let's see how we can make the documentation clearer.  I think it takes only
these two additional sentences in the description:

"Each character in the expanded value of @var{parameter} is tested against
@var{pattern}, and, if it matches the pattern, its case is converted.
The pattern should not attempt to match more than one character."

And, for what it's worth, the number of characters in a [...] pattern does
not matter: a bracket expression can only ever match a single character.
