`--help` option and naked `mdedup` calls must print the same help screen

[kdeldycke]

Just found out the issue: mdedup --help and naked mdedup calls doesn't not produces the same output.

The fix would be to wrap/patch the original --help option call and plug in there the code producing the enhanced help screen from:

mail-deduplicate/mail_deduplicate/cli.py

Lines 276 to 304 in f423b41

	# Print help screen and exit if no mail source provided.
	if not mail_sources:
	# Extract keywords
	keywords = collect_keywords(ctx)
	# Apply dynamic style to help screen.
	click.echo(colorized_help(ctx.get_help(), keywords))
	# Produce the strategy reference table, with grouped aliases.
	method_to_ids = {}
	for strat_id, method in sorted(STRATEGY_METHODS.items(), reverse=True):
	method_to_ids.setdefault(method, []).append(strat_id)
	strat_table = sorted(
	[
	("|".join(strat_ids), " ".join(method.__doc__.split()))
	for method, strat_ids in method_to_ids.items()
	]
	)
	# Reuse click machinery to format CLI helper output.
	formatter = ctx.make_formatter()
	# XXX Seems to have no effect. Should have introduced an empty line
	# before section.
	formatter.write_paragraph()
	with formatter.section("Available strategies"):
	formatter.write_dl(strat_table)
	click.echo(colorized_help(formatter.getvalue().rstrip(), keywords))
	ctx.exit()

This might be fixed naturally if there's progress on contributing som of my custom help screen highlight code to cloup, as discussed in: janluke/cloup#95

[kdeldycke]

The issue with help screens has been fixed by migrating to click-extra. The fix is available in the brand new release of mail-deduplicate 7.0.0.
