- * percent_x() takes a string and performs %<char> expansions. It aborts the
- * program when the expansion would overflow the output buffer. The result
- * of %<char> expansion may be passed on to a shell process. For this
- * reason, characters with a special meaning to shells are replaced by
- * underscores.
- *
- * Diagnostics are reported through syslog(3).
