minor fix in usage message

Log message:

Version 0.5.0

 Major changes:

   Lots of tasks from TODO are implemented.

   pkg_src_fetch_var:
      - minor fixes in comments
      - new options -h|--help for use message
      - new options -f|--fields|-v|--vars for specifying a list of fields
        to be generated. By default PKGNAME and PKPATH
        are generated as earlier versions did.

        Example:
          echo 'wip/distbb' | \
          pkg_src_fetch_var -f='PKGNAME PKGPATH DEPENDS BUILD_DEPENDS'

      - bmake '+=' operator is also supported

   pkg_src_summary:
      - new options -h|--help for use message
      - new options -f|--fields for specifying a list of fields
        to be generated. By default PKGNAME and PKPATH
        are generated as earlier versions did.
      - 'print-summary-data' pkgsrc target is not used anymore.
        Instead, variable's values are obtained directly by bmake.

        Side effect/incompatibility: NOTFOR and ONLYFOR are set to
        <empty_string> instead of 'any' string in case
        NOT_FOR_PLATFORM and ONLY_FOR_PLATFORM are not specified.

   pkg_micro_src_summary:
      - new options -f|--fields for specifying a list of fields
        to be generated. By default PKGNAME and PKPATH
        are generated as earlier versions did.

        Example:
          pkg_micro_src_summary -f 'PKGNAME PKGPATH DEPENDS BUILD_DEPENDS' \
                                   lang/lua wip/distbb
      - In case pkg_src_fetch_var failes pkg_micro_src_summary fallbacks
        to pkg_src_summary.

Log message:
minor clean-ups

Log message:

version -> 0.4.6

   fix for pkg_summary4view: doesn't depend on input fields order.
   fix for pkg_src_summary: PKGNAME and PKGPATH are printed first.

Log message:

version -> 0.4.5

   Both pkg_micro_src_summary and pkg_src_summary generate
   nicely formatted bmake failures to stderr.
   (will be used by future versions of distbb) 

Log message:

FIX: Converting summary_data to pkg_summary(5) can also fail.
    In this case only one package should be skipped, but
    pkg_src_summary should continue its work.
