help2man: updated to 1.47.15

help2man (1.47.15) unstable; urgency=medium

  * Use the package name and version as the default for --source (was
    program).
  * Support packages in version strings without the GNU or Free prefix.
  * Allow an optional second dash to separate the package name from the
    version for multi-word packages: "program - package name - version".

help2man (1.47.14) unstable; urgency=medium

  * Revert --version parsing change from 1.47.13, which had unintended
    consequences for some version strings.  In short, it is not possible
    to unambiguously determine the split between the package/program name
    and version in some of the supported formats.  Multi-word package
    names are supported only in the "program (GNU package) version"
    variant
