Details:

The attached patch has the following parts:

* src/libs/libgroff/glyphuni.cpp
  This is the main mapping change.
* src/libs/libgroff/uniglyph.cpp
  The reverse direction for consistency.
* tmac/an-old.tmac tmac/doc.tmac-u PROBLEMS
  Remove redefinitions that are now obsolete
  because they are now done for all macro sets.
* man/groff_char.7.man font/devutf8/NOTES
  Adjust documentation for \- and U+002D.

No changes are needed for devascii, devlatin1, devhtml.
As far as i understand, devps and devpdf are fine, too.
A brief look at some of the vendor-specific devices
gives me the impression that those probably don't need
changes, either.  If somebody who is more experienced
with the ps, pdf, and vendor-specific drivers could
cross-check, that would be welcome.  Otherwise, any
omissions in those other drivers can be fixed later
if and when any are found.

The motivation for this change is that right now, as observed by Ralph
Corderoy, there is no way to request a U+002D HYPHEN-MINUS output glyph that
works across all macro sets and devices, even though that is often needed when
documentation programming language syntax or quoting code samples.  For more
details, see the ongoing dicussion on <address@hidden>.
