    lib/libc/stdio       vsnprintf.c 
  Log:
  MFC revision 1.22: When size is 1 should just null terminate the string.
  
  This fix has the side effect of making vsnprintf() properly return the
  length of the string that would have been created if the buffer were
  infinite length when the passed size is 1.  Previously, it would
  erroniously return 0 which causes auto-extending sbufs to misbehave in
  userland apps linked against libsbuf.
