[PATCH] userdiff: fix HTML hunk header regexp

Current HTML header regexp doesn't match headers without attributes.

So it fails to match <h1>...</h1>, while <h1 class="smth">...</h1> matches.
The fix makes attributes optional.
The regexp is still far from perfect, but now it at least handles the
common case.
