    regex integer -> string

Parameters:

    in:  regex: a regular expression generated by "regcomp_"
      integer code of what went wrong.
      out:  string of error description.

      Examples:  preparation:
      (\() regcomp_	 ->  8 False
      pop
      now there's a wrong regex and an errorcode on the stack
      :regerror = -> Unmatched ( or \(

    no known ;-)

Diagnostics:

    no errors raised	- this _is_ a command to check an error!

Remarks:

      See man regerror for further details on POSIX regerror.
      Note that the command "regcomp" performs automatic error checking. You should
      probably use "regcomp", not "regcomp_".
