[Rd] wish: print.condition and html (PR#7848)

print.condition prints out error messages enclosed in angle brackets as in:

> simpleError("Sigh, yet another error...")
<simpleError: Sigh, yet another error...>

If R is used to generate HTML output (R2HTML or Rpad), then the error messages
get hidden because browsers will skip right over the "<simpleError: Sigh, yet
another error...>".

Suggestion: remove the angle brackets or replace with square brackets or
something else that won't confuse a browser.
