fix for nodeSize computation, used to determine if

Browse Source 
a node fits on one line:
- for purposes of measuring the node size in text,
  don't generate html or use a styler that could
  generate html as it will lead to overly large
  sizes

A consequence of this bug is that source code displayed
with godoc may show functions that fit on one line in
the source on multiple lines.

This change causes no difference to the gofmt formatting
of any files in src or misc.
