Documented unexpected behavior when calc is running in
"shell script mode" and the prompt builtin function is used
without the -p flag. Updated help/prompt, help/unexpected
and the calc man page accordingly.
Unless calc is given the -p command line option, calc will reopen
stdin as /dev/null instead of just closing stdin. This prevents
subsequent opens grabbing the 1st file descriptor.
Disable regress tests 4709, 4710, and 7763 because they print
multi-byte sequences, which are just fine for calc, the awk
used to evaluate the regression suite output in some legacy
systems report a "multibyte conversion failure".
Added a number of missing Makefile variables to the "make env" rule.
The man command is used to format the calc.1 man page into calc.usage.
The "help calc" command now prints the formatted calc man page (calc.usage).
The "help man" command now prints the formatted calc man page (calc.usage).
The "help usage" command now prints the formatted calc man page (calc.usage).
The file, calc.cat1, is formed by gzipping the calc.usage
formatted man page. The calc.cat1 is installed as the calc
cat section 1 man page.
Updated the Copyright string in version.c to refer to
the COPYING file and the "help copying" command.
Added calc.cat1 to .gitignore. Using "sort -d -u" to sort .gitignore content.
Avoiding use of modern [[ and ]] in Makefile for those legacy systems
whose shell do not support them. *sigh*
Fixed the order of "help full" to match the order of topics listed
buy the "help help" command.
Sorted the halias[] help topics table in help.c using sort -d -u.
Updated CHANGES.
Updated help/unexpected.
Added help files for d2g(), d2r(), g2d(), g2r(), r2d(), r2g().
Added regression test code for the same functions.
Fixed a few minor typos.
Some folks might think: “you still use RCS”?!? And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)
Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.
RCS served us well. But now it is time to move on. And so we are
switching to git.
Calc releases produce a lot of file changes. In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!
