In the sh(1) man page distributed with ksh 2014-01-14 beta, it looks
like part of the text for the description of .sh.match was
inadvertently transplanted to the description of .sh.version:

=====================================
.sh.match
        An indexed array which stores the most recent  match  and
        sub-pattern matches  after  conditional  pattern matches that match
        and after variables expansions using the operators
...
.sh.version
        The current version of this shell.  #, %, or /.  The 0-th element
        stores the complete match  and  the  i-th.  element  stores  the
        i-th submatch.  For // the array is two dimensional with the first
        subscript indicating the most recent match and sub-pattern match and
        the second script indicating which match with 0 representing the
        first match.  The .sh.match variable becomes unset when the variable
        that has expanded is assigned a new value.
