Replacing those makes sense. But replacing emdashes — which are a
distinct character that has no direct replacement in ASCII and which
people do *deliberately* use instead of hyphen-minus — does not.

Perhaps stick to those two, and any cases where an emdash or endash has
been used where U+002D HYPHEN-MINUS *should* have been used.

And please fix your cover letter which made no reference to 'grep', and
only presented a completely bogus argument for the change instead.
