Sanitize underscores as core does, to not create broken links

Browse source 
Core sanitizes link targets and removes double spaces and underscores.
But the corresponding id="…" attributes are not sanitized the same
way. This results in broken links. This patch is not perfect (two
references with name="a_b" and name="a__b" will conflict), but the
best solution I can think of at the moment.
