update GitHub workflows to use actions/checkout@v5

In preparation to fix issue #47, we:

Fix a minor typo in `Makefile.config`.

Move `stringindex(char *format, char *test)` from `str.c` into `codegen.c`
as static function.

Expand `STR_TABLECHUNK` from `1<<10` to `1<<16`.

Identify with an XXX comment, a problematic `realloc()` call in the
`addstr(STRINGHEAD *hp, char *str)` function of `str.c`.

Move the `charstr(int ch)` in `str.c` above the only function that uses
it, `addliteral(char *str)`, and make it a static function.

Improved comments about return values for `str.c` functions that
work on STRINGHEAD pointers.

 Typically the largest unsigned long is typedefed to FULL.  The following
 macros are useful in dealing with this data type:
 
-	MAXFULL		(largest positive FULL value)
-	MAXUFULL	(largest unsigned FULL value)
-	zgtmaxfull(z)	(number is > MAXFULL)
-	zgtmaxufull(z)	(number is > MAXUFULL)

+        zgtmaxlong(z)   (number is > MAXLONG, largest long value)
+        zgtmaxulong(z)  (number is > MAXULONG, largest unsigned long value)
 
 If zgtmaxufull(z) is false, then one may quickly convert the absolute
 value of number into a full with the macro:
 
-	ztofull(z)	(convert abs(number) to FULL)
-	ztoulong(z)	(convert abs(number) to an unsigned long)
-	ztolong(z)	(convert abs(number) to a long)

+        ztoulong(z)     (convert abs(number) to an unsigned long)

 This returns a pointer to a number which has the value 1.  Because of the

 A better way to create NUMBERs with particular values is to use the itoq,
 iitoq, or str2q functions.  Using itoq makes a long value into a NUMBER,
 using iitoq makes a pair of longs into the numerator and denominator of a
 NUMBER (reducing them first if needed), and str2q converts a string representing
