New Revision: 275729
URL: https://svnweb.freebsd.org/changeset/base/275729
Log:
Increase the buffer size to keep the list of programm names when
parsing programm specification. It is safe to not check out of bounds
access, because !isprint(p[i]) check will stop reading, when '\0'
character will be read from the input string.
