doc/meref.me.in: Fix momentary lapse of reason.
Partially revert commit 1728f9229a, 5 October. I must have eaten the
wrong mushrooms; the correct argument order was "h w" all along. That
is what pic(1) produces and what me(7) must accept.
DWB 3.3 pic:
pltroff.c: printf(".PS %.3fi %.3fi %s", yconv(ymin), xconv(xmax), s);
GNU pic:
src/preproc/pic/troff.cpp: printf(".PS %.3fi %.3fi", height, width);
4.4BSD e.tmac:
.de PS \" *** start picture: $1=height, $2=width in units or inches
[...]
.nr g7 \\$2
.in (\\n(.lu-\\n(g7u)/2u
.ne \\$1u
GNU e.tmac:
.de PS \" *** start picture: $1=height, $2=width in units or inches
[...]
.nr g7 \\$2
.in (u;\\n(.l-\\n(g7>?0/2)
.ne \\$1u

- * doc/meref.me.in: Fix documentation errors.
- (Preprocessor Support) <PS>: Swap argument order (width comes
- first), note empty defaults, and (vaguely) describe their
- purpose. DWB and GNU pic semantics evidently diverge here.
+ * doc/meref.me.in: Fix documentation error.
(Summary) <\_>: Describe as "underrule", not "underscore".
These are distinct: the latter is a glyph; the former is drawn
by typesetters and rendered with SGR attributes on terminals.
