title: cleanup snprintf() convention
desc: |-
  There seem to be to variants of snprintf (and its friends): some ensure a
  NUL terminator is added when truncated and others do not.
  
  The most portable way seems to be to::
  
    char buf[256];
  
    snprintf(buf, sizeof(buf), "format", args);
    buf[sizeof(buf) - 1] = (char) 0;
  
  Using sizeof(buf) - 1 for size may cause a NUL terminator to appear at
  the second to last character of buf in some cases.
  
  Document in code-issues.txt.

    Also the return value of snprintf (and its friends) seems to vary between
    implementations when the string is truncated.  This is mostly the case with
    old environments.  Document that snprintf return value is not to be trusted
    without care.
