We cannot have a test that destroys eg. /etc/passwd if someone
runs it as root.

* LC_NUMERIC radix issue.
According to https://pubs.opengroup.org/onlinepubs/7990989775/xcu/awk.html
The period character is the character recognized in processing awk
programs. Make it so that during output we also print the period
character, since this is what other awk implementations do, and it
makes sense from an interoperability point of view.
* print "T.builtin" in the error message
* Fix backslash continuation line handling.
* Keep track of RS processing so we apply the regex properly only once
per record.

enhancement. (#72)
* - enhance fpe handler to print the error type
- cleanup argument parsing
- dynamically allocate program filename array
* bison uses enums now, not #define's, make it work with that.
* We need to use either the enums or the defines but not both. This
is because bison -y will create both enums and #defines, while bison
without -y produces only the enums, and byacc produces just #defines.
* fix indentation
* Set the tokentype when we have a match in the scan, and reset it later
when we decide that the match was bad. Fixes nbyacc.
* - don't use pattern rules for portability
- try to move both flavors of generated names for portability
* Amend tests for the new error messages

* Add a test for german case folding.
* Add a function to copy a string with a string with a larger allocation
(to be used by the case folding routines)
* Add printf attributes to the printf-like functions and fix one format
warning
* Cleanup the tempfree macro
* make more functions static
* rename fp to frp (FRame Pointer) to avoid shadowing with fp (File Pointer).
* add more const
* fix indent in UPLUS case
* add locale-aware case folding
* make nfiles size_t
* fix bugs in file closing:
- compare fclose to EOF and pclose to -1
- use nfiles instead of FOPEN_MAX in closeall
- don't close files we did not open (0,1,2) fpurge/fflush instead
* - use NUL instead of 0 for char comparisons
- add ISWS() macro
- use continue; instead of ;
* Check for existance of the german locale before using it.
* Add missing parentheses, thanks Arnold.

An input/output error indicates a fatal condition, even if it
occurs when closing a file. Awk should not return success on I/O
error, but treat I/O errors as it already treats write errors.
Test case:
$ (trap '' PIPE; awk 'BEGIN { print "hi"; }'; echo "E $?" >&2) | :
awk: i/o error occurred while closing /dev/stdout
source line number 1
E 2
The test case pipes a line into a dummy command that reads no
input, with SIGPIPE ignored so we rely on awk's own I/O checking.
No write error is detected, because the pipe is buffered; the
broken pipe is only detected as an I/O error on closing stdout.
Before this commit, "E 0" was printed (indicating status 0/success)
because an I/O error merely produced a warning. A shell script
was unable to detect the I/O error using the exit status.

On case-insensitive file systems (i.e.: macOS), T.concat and
t.concat are the same file, so these conflicted. This commit
renames T.concat to avoid the conflict.

Further simplify printf % parsing by eating the length specifiers
during the copy phase, and substitute 'j' when finalizing the format.
Add some more tests for this.
