Fix POD syntax error.
v0.087_04

      !! DEVELOPER RELEASE !!

      INCOMPATIBLE CHANGES:

      * Both the "pull" and "add" commands will no longer fetch development
      prerequisites by default.  If you want to have them, then add the
      --with-development-prerequisites (or --wd) option.

      NEW FEATURES:

      * The "add" command now has an experimental --no-index option to exclude
      certain packages from the index.  This is useful when Pinto finds
      packages in your distribution that it should not.  Thanks to Todd Chapman
      for the great suggestion.

      * The "diff" command now accepts revision IDs as arguments, so you can
      compare any two arbitrary revisions.  Revision IDs can be truncated to
      uniqueness.  This feature was generously funded by a grant from TPF.

      * The "new" command now accepts a --target-perl-version option to set
      the target perl version of the new stack.  This affects how Pinto
      decided if a prerequisite is satisfied by the core.  If you do not
      specify the --target-perl-version, then it defaults the global value
      that is set in the repository configuration file.

      ENHANCEMENTS:

      * Optimized some queries to make it faster to register packages on a stack.
      In the best cases, performance has improved by about 150%.  But in the
      average case, the limiting factor is fetching and unpacking the upstream
      distribution, so you'll only see a slight improvement there.

      * If your username contains non-alphanumeric characters, they will be
      stripped out when used as your author identity.  This is because the
      CPAN toolchain requires author ids to be alphanumeric.  Thanks to
      @chiselwright and @cebjyre.

      * The "statistics" command now accepts a stack name, so you can see
      the figures for any stack in the respository, not just the default
      stack.  This was a silly omission.  I don't know why I left it out.

      BUG FIXES:

      * You can now edit the commit message when pinto is reading input from
      a file or pipe, as long as STDOUT is connected to a terminal.  You
      can always just use the -m or -M options if you don't want to edit
      the message.

      INTERNAL CHANGES:

      * Pinto no longers stores the file path and SHA digest of every
      package it sees in the META, since many distributions on CPAN don't have
      the right paths in there anyway.  This allows Pinto to index some
      (technically broken) distributions that it otherwise couldn't.  Pinto
      was never really using this information anyway, and it will probably be
      removed from the schema entirely in the next major upgrade cycle.
