svn commit: r215921 - stable/8/usr.bin/locate/locate

[Nathan Whitehorn]

Author: nwhitehorn

New Revision: 215921
URL: http://svn.freebsd.org/changeset/base/215921

Log:
  MFC r215752:
  Properly use SCHAR_MAX instead of CHAR_MAX for 0x7f. This fixes operation
  of locate(1) on systems on which char is unsigned by default (ARM and
  PowerPC).
