+ [tmac]: Adjust editor file encoding hints.
+
+ * tmac/cs.tmac: Tell Vim the file is "iso-8859-2" (ISO Latin-2).
+ * tmac/en.tmac: Stop telling Emacs the file is "latin-1"; it's
+ ASCII.
+ * tmac/fr.tmac: Tell Vim file is "iso-8859-15" (ISO Latin-9).
+
+ Vim users may need to use ":e ++enc=iso-8859-2", for instance,
+ to see correct glyphs.

+
+ Determine the groff locale (default input language) using the
+ system locale. Use the environment if possible. Try LC_ALL
+ first, then LANG. "C" means English (en). Otherwise, only the
+ first two characters of the locale name are used.
+
+ Unrecognized locales (those without a supporting xx.tmac file)
+ are ignored, and groff falls back to English.
+
+ Those who want groff's default locale to differ from LC_ALL/LANG
+ should edit the troffrc file to source the appropriate groff
+ locale macro file (cs.tmac, de.tmac, den.tmac, fr.tmac, ja.tmac,
+ sv.tmac, zh.tmac).
+
+ The first-order determinant of hyphenation points is language,
+ not territory. Use ISO 639 2-letter language codes for
+ hyphenation and exception patterns instead of ISO 3166 2-letter
+ territory codes.
+
+ * tmac/*.us: Rename *.us files to *.en.
+ * tmac/troffrc: Change hyphenation language "us" to "en".
+ * tmac/en.tmac: Add English localization file. Set hyphenation
+ mode to 4.
+ * tmac/troffrc: Derive groff locale from system.
+
+ * doc/groff.texi (Manipulating Hyphenation):
+ * man/groff.7.man (Hyphenation):
+ * man/groff_diff.7.man (Implementation differences): Refer to
+ "U.S. English" hyphenation patterns as simply "English"; they
+ will be mostly correct for Commonwealth English as well, and no
+ alternative English hyphenation patterns for other territories
+ are available.
+
+ * doc/groff.texi (Manipulating Hyphenation):
+ * man/groff_diff.7.man (New requests): Note that default
+ hyphenation mode depends on the language used on the system.
+ Add concept index entry for localization. Add file index
+ entries for the locale macro files (cs.tmac, etc.). Add
+ environment variable index entries for LANG and LC_ALL.
+ Describe how groff's idea of the locale is determined. Update
+ to reflect rename of English hyphenation patterns and .hla
+ identifier from "us" to "en".
+
+ * src/roff/groff/tests/localization_works.sh: Add 10 test cases.
+ * src/roff/groff/groff.am (groff_TESTS): Run test.
+
+ * tmac/LOCALIZATION: Rewrite.
+
+ Fixes <https://savannah.gnu.org/bugs/?59814>.

+o The groff locale (the default input language) is now determined using
+ the system locale. The LC_ALL and LANG environment variables are
+ checked, in that order. If set, the value's first two characters
+ determine the groff locale. If these variables are not set, if the
+ first one found is set to "C", or if no groff localization file exists
+ for the language, groff falls back to English, loading en.tmac.
+
+ Those who want groff's default locale to differ from LC_ALL/LANG
+ should edit the troffrc file to source the appropriate groff locale
+ macro file (cs.tmac, de.tmac, den.tmac, fr.tmac, ja.tmac, sv.tmac,
+ zh.tmac).
+
+ The default hyphenation mode (as used by the .hy request) for users of
+ English is thus changed from "1", which was inappropriate for the
+ TeX-based hyphenation patterns groff has used since at least 1991, to
+ "4". However, calling .hy without an argument remains synonymous with
+ ".hy 1".
+
o A new read-only register ".cp" is implemented. Within a .do request,
"\n[.cp]" holds the saved value of compatibility mode. See
groff_diff(7) or the groff Texinfo manual for rationale, use case, and
