narrow: add option for automatically removing unused includes
It's been a somewhat common request among our users to have Mercurial
automatically pick includes to remove. This patch adds an option for
that: `hg tracked --auto-remove-includes`. I'm not sure if this is the
right name and semantics for it. Perhaps the feature should also add
excludes of large subdirectories even if other files in the include
are needed? Narrow clones are experimental, so we can change the name
and/or semantics later if necessary.
