svn commit: r227090 - head/lib/libc/stdlib

[Ed Schouten]

Author: ed
Date: Fri Nov  4 19:56:34 2011
New Revision: 227090
URL: http://svn.freebsd.org/changeset/base/227090

Log:
  Fix a warning emitted by Clang.
  
  The size passed to strlcat() must depend on the input length, not the
  output length. Because the input and output buffers are equal in size,
  the resulting binary does not change at all.
