[PATCH 7/8] split: don't rely on knowledge that INT_BUFSIZE_BOUND <= SIG2STR_MAX

[Jim Meyering]

From: Jim Meyering <address@hidden>

* src/split.c (closeout): SIG2STR_MAX is a buffer size, so there's
no need to add 1.  However, since we may also write the decimal
representation of an "int" into this same buffer, include
INT_BUFSIZE_BOUND in the equation.
