[PATCH v3 0/2] Refactor and improve full help output from tools

[Paul Barker]

Changes from v2:
  * Handle the case where `PAGER` is unset. For some absolutely crazy reason
    `shlex.split(None)` reads the string to split from stdin so we need to
    ensure that `os.getenv()` returns an empty string instead of None if `PAGER`
    is unset.

Changes from v1:
  * Collected the full help printing code from patman, buildman & binman into a
    single function so that when support for PAGER containing arguments is added
    it applies to all the relevant tools.
