move anchor-link off of heading text

[minrk]

avoids confusion about where to click, matching Sphinx-style output with a clickable ¶, only drawn on hover.

Also moves the relevant style to textcell.less, since it only affects heading cells.

merging soon if no objection

No objection. Could the same thing be done purely with css ?

heading-anchor{display:none}
h1:hover.heading-anchor{display:visible}

instead of binding one more js event?

might be, I will give it a try.

[minrk]

yup, much better. Had to use visibility instead of display for some weird reason, because toggling display wouldn't draw it on the same line.

[Carreau]

which is faster .text(...) or .html(...) I guess here you use html() to escape to the html sequence ...

[minrk]

might as well use text, I guess

Ah, because display can be block or inline... maybe.

Good to merge for me.

Ok, merging.
