help config: explain that config files do not exist by default

Inspired by critique given on StackOverflow where a user writes:

  I can have a good guess at what "%USERPROFILE%" might signify but
  none of the files listed in the "hg help config" output exist after
  running the installer. Previous experience would suggest that
  missing files mean something somewhere has gone seriously wrong.

test command parsing and dispatch

  $ "$TESTDIR/hghave" no-outer-repo || exit 80

  hg cat [OPTION]... FILE...
  
  output the current or given revision of files
  
      Print the specified files as they were at the given revision. If no
      revision is given, the parent of the working directory is used, or tip if
      no revision is checked out.
  
      Output may be to a file, in which case the name of the file is given using
      a format string. The formatting rules are the same as for the export
      command, with the following additions:
  
      "%s"  basename of file being printed
      "%d"  dirname of file being printed, or '.' if in repository root
      "%p"  root-relative path name of file being printed
  
      Returns 0 on success.
  
  options:
  
   -o --output FORMAT        print output to file with formatted name
   -r --rev REV              print the given revision
      --decode               apply any matching decode filter
   -I --include PATTERN [+]  include names matching the given patterns
   -X --exclude PATTERN [+]  exclude names matching the given patterns
  
  [+] marked option can be specified multiple times
  
  use "hg -v help cat" to show global options
