The  syntax of logical  pathname namestrings  specifies that  the only
characters valid in words  (or wildcard-words) are UPPER CASE letters,
digits and dash (and star in wildcards).

But at the same time, the version may be written both in lower case or
upper case: 'newest' or 'NEWEST'. :-)

Do not adjust your mind, there is a fault in reality.

   19.3.1.1.7 Lowercase Letters in a Logical Pathname Namestring

   When parsing words and wildcard-words, lowercase letters are
   translated to uppercase.

Interestingly, that refers only to namestrings, not to components as
supplied to make-pathname.  I'd hope that a similar conversion is done
to them, though I can't find anything that mandates it.
