	 * WordPress renders the plugin information rows in the plugins page in <tr> elements as follows:
	 *
	 * - If the plugin needs update, the <tr> will have an "update" class. This will prevent the lower
	 *   border line to be drawn. Later an additional <tr> with an "update available" warning will be rendered,
	 *   it will have a "plugin-update-tr" class which will draw the missing lower border line.
	 * - Otherwise, the <tr> will be already drawn with the lower border line.
	 *
	 * This is a problem for our rendering of the "plugin is incompatible with X features" warning:
	 *
	 * - If the plugin info <tr> has "update", our <tr> will render nicely right after it; but then
	 *   our own "plugin-update-tr" class will draw an additional line before the "needs update" warning.
	 * - If not, the plugin info <tr> will render its lower border line right before our compatibility info <tr>.
	 *
	 * This small script fixes this by adding the "update" class to the plugin info <tr> if it doesn't have it
	 * (so no extra line before our <tr>), or removing 'plugin-update-tr' from our <tr> otherwise
	 * (and then some extra manual tweaking of margins is needed).
