Without setting HGPLAIN, the user's environment leaks into hg invocations, which means that the output may not be in the expected format. HGPLAIN is the Mercurial-recommended solution for this in that it's intended for uses by scripts and programs which are looking to parse Mercurial's output in a consistent manner.
