    usr.bin/xargs        strnsubst.c 
  Log:
  Fix a buffer overflow.  This is the same bug as is corrected in rev.
  1.7, but the correction is different: Rather than making sure the
  string we're constructing doesn't grow too large, we realloc() to make
  sure the buffer is large enough.
  
  This violates the IEEE Std 1003.1-2004 standard, but retains backwards
  compatability.
