/**
 * tal/str - string helper routines which use tal
 *
 * This is a grab bag of functions for string operations, designed to enhance
 * the standard string.h; these are separated from the non-tal-needing
 * string utilities in "str.h".  Each string created by this library
 * will have tal_count() equal to strlen() + 1 (assuming you didn't create
 * a string containing a NUL, such as using tal_fmt("%c", 0)).
 *
 * Example:
 *	#include <ccan/tal/str/str.h>
 *	#include <ccan/tal/grab_file/grab_file.h>
 *	#include <err.h>
 *
 *	// Dumb demo program to double-linespace a file.
 *	int main(int argc, char *argv[])
 *	{
 *		char *textfile;
 *		char **lines;
 *
 *		if (argc > 2)
 *			errx(1, "Takes 0 or 1 arguments");
 *		// Grab lines in file.
 *		textfile = grab_file_str(NULL, argv[1]);
 *		if (!textfile)
 *			err(1, "Failed reading %s", argv[1]);
 *		lines = tal_strsplit(textfile, textfile, "\n", STR_EMPTY_OK);
 *
 *		// Join them back together with two linefeeds.
 *		printf("%s", tal_strjoin(textfile, lines, "\n\n", STR_TRAIL));
 *
 *		// Free everything, just because we can.
 *		tal_free(textfile);
 *		return 0;
 *	}
