	* gpinyin.pl: Report groff version number along with this
	program's own when not run from source tree.  Drop dead code.
	Bump micro version number to reflect recent restructuring.

2022-10-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	Make gpinyin script stand alone.

	* subs.pl: Delete, moving its content into...
	* gpinyin.pl: ...here.
	(vowel_t): Use explicit list with `my`.
	(vowel_n, vowel_t): Declare local scalar `$vowel_with_tone`
	using `my`.
	* gpinyin.am (dist_gpinyin_DATA): Delete.

2022-05-03  G. Branden Robinson <g.branden.robinson@gmail.com>

	* gpinyin.am (gpinyin): Fix missing dependency on
	`$(SH_DEPS_SED_SCRIPT)`.

2021-05-11  G. Branden Robinson <g.branden.robinson@gmail.com>

	* gpinyin.1.man: Render the tone mark table only if the output
	device might be capable.

	Fixes <https://savannah.gnu.org/bugs/index.php?55215>.

2021-05-10  G. Branden Robinson <g.branden.robinson@gmail.com>

	* gpinyin.1.man: Work around inability of grops and gropdf to
	construct some Unicode composite characters.  Use groff
	composite special characters for "a" with acute and grave
	accents, and define strings for "a" with macron (overline) and
	with háček/caron accents.  Use different string definitions for
	nroff and troff modes so we don't regress UTF-8 terminal output.

2021-05-10  G. Branden Robinson <g.branden.robinson@gmail.com>

	* subs.pl (vowel_t): Fix incorrect rendering of base glyph 'U',
	which was being forced to lowercase when a dieresis and tone
	mark were both being applied.  This caused the tone mark to
	overlap the dieresis, so decrease the font size of the base
	glyph even more to compensate.  The result is ugly but
	comprehensible.

	See <https://savannah.gnu.org/bugs/?57524>, partially mitigated
	but not completely resolved.

2021-05-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	* subs.pl (%tones1_Unicode): Fix copy and paste error.  Emit
	U+01D5 (Latin capital letter u with dieresis and macron) for Ü
	with tone 1, instead of U+016A (Latin capital letter u with
	macron).

	Fixes <https://savannah.gnu.org/bugs/?60562>.

2021-05-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	* subs.pl (handle_word): Emit \[cq] instead of \[aq] when
	interpolating an apostrophe before a vowel.

	Fixes <https://savannah.gnu.org/bugs/?60561>.

2021-05-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	* subs.pl (%tones_glyphs, %tones4_glyphs): Fix hash keys to use
	the groff dotless i special character into which a lowercase "i"
	has already been transformed instead of 'i' itself.
	(vowel_n, vowel_t): Rename variable so that tone-transformed
	vowel is stored separately.  Add "or warn" to test the result
	and cheaply assert that we got a string back from our hash
	lookup on the vowel.

	Fixes <https://savannah.gnu.org/bugs/?60560>.

2021-01-06  Colin Watson <cjwatson@debian.org>

	* gpinyin.pl: Avoid Perl's unsafe "<>" operator.

	The "<>" operator is implemented using the two-argument form of
	"open", which interprets magic such as pipe characters, allowing
	execution of arbitrary commands which is unlikely to be
	expected.  Perl >= 5.22 has a "<<>>" operator which avoids this,
	but also forbids the use of "-" to mean the standard input,
	which is a facility that the affected groff programs document.

	ARGV::readonly would probably also fix this, but I fundamentally
	dislike the approach of escaping data in preparation for a
	language facility to unescape it, especially when the required
	escaping is as non-obvious as it is here.  (For the same reason,
	I prefer to use subprocess invocation facilities that allow
	passing the argument list as a list rather than as a string to
	be interpreted by the shell.)  So I've abandoned this dubious
	convenience and changed the affected programs to iterate over
	command-line arguments manually using the three-argument form of
	open.

	Fixes <https://savannah.gnu.org/bugs/?55557>.
