Make `test-groff' work again -- previously, wrong paths have been

used.  Additionally, it can now be called from anywhere.

* test-groff.in: Don't test for groff binary.  This is no longer
necessary since the proper paths are determined by `configure'.
(EXEEXT): Removed.  No longer used.
(srcdir, builddir): Use values provided by the configure script.
(XENVIRONMENT): Updated.

* INSTALL: Updated.


Make .tag and .taga work for all devices (but only grohtml actually
handles them).

* src/devices/grohtml/post-html.cpp: s/html-tag/devtag/.
(text_glob::is_br, page::add_tag, html_printer::troff_tag,
html_printer::handle_assertion): Don't use hard-coded string
lengths.
(html_printer::lookahead_for_table): Reset `tbl' properly if
necessary.
(html_printer::devtag): New function, handling `devtag'.
(html_printer::special): Don't handle `html-tag'.

* src/include/printer.h, src/libs/libdriver/printer.cpp
(printer::devtag): New virtual function.

* src/libs/libdriver/input.cpp (parse_x_command) <'X'>: Handle
`devtag'.

* src/roff/troff/env.cpp, src/roff/troff/mtsm.cpp,
src/roff/troff/node.cpp: s/html-tag/devtag/.

* src/roff/troff/input.cpp (tag, taga): Always call
curenv->add_node.

* tmac/an-old.tmac, tmac/s.tmac, tmac/troffrc-end: Use DEVTAG*
macros instead of HTML-TAG*.

* tmac/devtag.tmac: New file, defining the DEVTAG-* macros.

* tmac/www.tmac: Load devtag.tmac.
Replace HTML-TAG* macros with DEVTAG* macros.
(HTML, HTML-NS): Changed definitions.
(URL): Use HTML-NS.
(HTML-TAG, HTML-TAG-NS, HTML-TAG-NEXT): Removed.

* tmac/Makefile.sub (NORMALFILES): Add devtag.tmac.

+    Description
+------------------------------------------------------------------------
+
+A simple set of macros to provide markup devices (currently only grohtml)
+with tags that define the meaning of the formatted text and also
+basic formatting instructions. It generalises the tag concept used within
+grohtml and in the future it is hoped that more markup based devices
+can capitalise on this work. It also clearly defines those tags which are
+honoured by grohtml. Note that not all tags are included here. Some
+of the grohtml specific tags (header specific and jobname etc) are
+called directly from within www.tmac. The tags defined here are
+reasonably generic and could be applied to the -Tdoc device when it
+is written.
