        src/bin/sh: var.c

Log Message:
Fix an off by one buffer length problem.   Fortunately, it was off by
one in the "safe" way (it was ensuring the buffer always ended in 2 \0
characters ... one is enough.)   This could affect the expansions of
LINENO RANDOM and SECONDS, though only if they have at least 8 digits
(and then, only sometimes).   RANDOM thus is safe, as it never produces
a number with more than 5 digits, you'd need a script with 10000000
lines before there might be an issue with LINENO (and even autoconf
generated scripts don't generally get that bit) and a shell would need
to be running for almost 4 months for SECONDS to climb that high.

Nevertheless: XXX pullup -8.
