Certain accelerators unusable in markup_accel_tooltip

[jeremypw]

What Happened?

Setting "less" (<) as an action accelerator is valid (and works) but trying to generate a tooltip with this accelerator fails as it generates invalid markup (<span weight="600" size="smaller" alpha="75%"> <</span>).

Presumably the same would happen with e.g. "greater" (>).

Steps to Reproduce

app.set_accels_for_action (action_name, {"less"});

....

tooltip_markup = Granite.markup_accel_tooltip (app.get_accels_for_action (action_name), text);

Expected Behavior

All valid accelerators should be able to be shown in tooltips (or should be omitted from the tooltip while showing other accels for the same action).

OS Version
