[PATCH 01/34] Revise approach to man(7) `EX`/`EE` macros.

[G. Branden Robinson]

Trying to define `EX` and `EE` macros only if the underlying formatter
didn't did not work out well.  mandoc(1) (which _has_ supported them for
a decade, since 1.12.2 on 2013-10-05) has a "-T lint" mode that gets
confused by nested conditional blocks in branches that _aren't_ taken.
It threw scary "ERROR" diagnostics in response to my earlier approach.
mandoc(1) maintainer Ingo Schwarze identified this as a bug, but there's
another issue: it's hard to find man page formatters these days that
_don't_ support these macros.  groff, mandoc, Heirloom Doctools, Plan 9,
and even Documenter's Workbench all do.

It therefore seems better to just assume support for `EX` and `EE`.

* man/MKada_config.in:
* man/clear.1: Drop conditional `EX`/`EE` macro definitions.

Dropping these macro definitions makes unnecessary the hoop we were
already jumping through to define a string to store the name of a
constant-width typeface, another portability challenge.

* man/MKada_config.in:
* man/clear.1: Drop definition of `CW` string.
