It's there (please excuse the ugly regexp):

# man sh | grep "\\\\\(H\|h\|w\|W\\|\\$\)"
               \H      The local hostname.
               \h      The fully-qualified hostname.
               \W      The final component of the current working directory.
               \w      The entire path of the current working directory.
               \$      Superuser status.  ``$ '' for normal users and ``# ''
# uname -a
