1. Avoid OOM in refill fuzz test …

   If two things happen at the same time:
   
   1. the input string has a huge prefix which is taken to be the
      indentation (such as “- - - - -”), and
   2. the wrapping with is set to something small (such as 0),
   
   then we can end up allocating an enormous amount of data in the
   output. The problem is that we add the indentation on every line of
   the output, and we end up with a huge number of lines when the line
   width is small.
   
   This was reported in OSS-Fuzz, please see
