* doc/misc/calc.texi (Customizing Calc): Document the new option.
* etc/NEWS: Document the new option.
* lisp/calc/calc.el (calc-inhibit-startup-message): New option to
inhibit Calc’s startup message.
(calc): Respect the option in Calc’s startup code.

'ert-with-message-capture'.
(calc-inhibit-startup-message): Test the new user option.
The current behavior of the functions 'calc-display-strings',
'strings', and 'bstrings' is to skip any vector containing
integers outside the Latin-1 range (0x00-0xFF). We introduce a
custom variable 'calc-string-maximum-character' to replace this
hard-coded maximum, and to allow vectors containing higher
character codes to be displayed as strings. The default value
of 0xFF preserves the existing behavior.
* lisp/calc/calc.el (calc-string-maximum-character): Add custom
variable 'calc-string-maximum-character'.
* lisp/calc/calccomp.el (math-vector-is-string): Replace hard-coded
maximum with 'calc-string-maximum-character', and the 'natnump'
assertion with 'characterp'. The latter guards against the
maximum being larger than '(max-char)', but not on invalid types of
the maximum such as strings.
* test/lisp/calc/calc-tests.el (calc-math-vector-is-string): Add
tests for 'math-vector-is-string' using different values of
'calc-string-maximum-character'.
* doc/misc/calc.texi (Quick Calculator, Strings, Customizing Calc):
Add variable definition for 'calc-string-maximum-character' and
reference thereof when discussing 'calc-display-strings'.
Generalize a comment about string display and availability of 8-bit
fonts.

* lisp/calc/calc-trail.el (calc-trail-kill): Remove the check
preventing the removal of the first trail line, which is no
longer relevant since commit 8e1376a391. (Bug#77816)
* lisp/calc/calc-ext.el (calc-init-extensions): Autoload calc-math
for math-ln-10.
* lisp/calc/calc-units.el (math-standard-units): Use new ln10
constant instead of ln(10) in the decibel definition.

* lisp/calc/calc-ext.el (calc-execute-extended-command): Use
M-x's ':affixation-function' to show the keybinding of the calc
command next to its name. (Bug#74829)
* lisp/calc/calc.el
(calc-embedded-open-close-new-formula-alist): Remove previously
introduced quotation marks, as they bring the width of the doc
string past 80.
'read-char' will no longer return -1 as of
ac82baea1c41ec974ad49f2861ae6c06bda2b4ed. This switches to a cleaner
method of detecting whether the end of a keyboard macro has been
reached.
* lisp/calc/calc-prog.el (calc--at-end-of-kmacro-p): New function.
(calc-kbd-skip-to-else-if): Use the function.

Fractions of the form 123⁄456 are handled as if written 123:456. Note
in particular the difference in behavior from U+2215 DIVISION SLASH
and U+002F SOLIDUS, which result in division rather than a rational
fraction.
* lisp/calc/calc-aent.el (math-read-replacement-list): Substitute a
colon for any fraction slash. (Bug#66944)

fraction types.

`math-read-preprocess-string` is one of the bottlenecks of `calc-eval`
and was unnecessarily slow even with no substitutions made.
This affected org-mode in particular, where `calc-eval` is called
repeatedly to recalculate tables.
Reported by Raffael Stocker who also wrote the unit tests here.

Immediately after `calc-mode' opens the minibuffer for input
(because you typed a digit, "e", etc), pressing backspace
should clear the minibuffer and return you to the *Calculator*
buffer. Instead, it leaves the minibuffer as-is and prints the
message "Text is read-only"; this is because the function used,
`erase-buffer', tries to erase the read-only minibuffer prompt.
Using `delete-minibuffer-contents' fixes this, since it doesn't
attempt to delete the prompt.
* lisp/calc/calc.el (calcDigit-backspace): Use
`delete-minibuffer-contents' instead of `erase-buffer'. (Bug#67395)
