Diomidis Spinellis f88b45d7df Prevent buffer overflow when forcibly terminating an escape character.
Obtained from:	OpenBSD
Note: In the case of a full buffer the OpenBSD implementation will
leave in the format string an invalid escape sequence.  This appears
to be harmless with our C library, but according to C99 this can
cause undefined behavior.
