help.merge-tools: do not double document merge tools
Merge tools were being double documented in help system output due
to functions being defined under multiple names in the merge tools
dictionary.
Establish a new dictionary for just the tools to document and
use it from the help system so we don't get double output.
Double documentation likely plagues other auto-documented items
as well. It might be a good idea to eventually compare function
instances to filter out duplicate entries from dictionaries
passed to ``makeitemsdoc``. However, without an easy way to break
ties, this may result in some functions being advertised over
their modern equivalents. This would be a noble patch series.
But it isn't one this author is willing to tackle at this time.
