A cell formatted Hidden on a protected sheet hid its formula but not its
Python code: display::formula_hidden only looked for a formula at the cell (a
Python cell was covered only while its result spilled), and the formula bar
had its own check for formulas alone. Both now treat Python code as they treat
a formula, so the formula bar shows nothing for a hidden Python cell, as it
does for a hidden formula. Editing the cell is refused as before, because it
is locked.
The grid's look() and print's cell_look() layered a rule's fill, font and
borders onto the cell style but not its num_fmt, so a cell under a rule with a
number format kept its own. Take the rule's code when it isn't General (in a
differential style General means "not set", as layer_under treats it).
Print also re-formatted every non-General cell from its own style through
display::cell_text; format with the look's code instead, through a new
display::value_text_as that value_text now calls (CSV/Text output unchanged).
Show Formulas keeps cell_text.

On a protected sheet a formula formatted Hidden still showed with Show
Formulas on, matched Find in formulas, and showed in the formula bar
when a cell of its spill range was selected.
