Peter Wemm e48f3cfbfc Rework previous commit.. I was confused by the number of diffs in the PR 
and forgot what I was trying to do originally and accidently zapped
a feature. :-]  The problem is that we are converting a counted buffer in
a malloc pool into a null terminated C-style string.  I was calling realloc
originally to shrink the buffer to the desired size.  If realloc failed, we
still returned the valid buffer - the only thing wrong was it was a tad
too large.  The previous commit disabled this.

This commit now handles the three cases..
1: the buffer is exactly right for the null byte to terminate the
string (we don't call realloc).
2: it's got h.left = 0, so we must expand it to make room. If realloc
fails here, it's fatal.
3: if there's too much room, we realloc to shrink it - a failed realloc
is not fatal, we use the original buffer which is still valid.
