- /*
-  * percent_x() takes a string and performs %x subsitutions.
-  * It aborts the program when the result of
-  * expansion would overflow the output buffer. Because the result of %<char>
-  * expansion is typically passed on to a shell process, characters that may
-  * confuse the shell are replaced by underscores.
-  * 
-  * Diagnostics are reported through syslog(3).
