styles: tweak Kate’s matched brackets
In the GtkSourceView’s Kate style, matched brackets were painted using
white font on black background. This made the (black) cursor hardly
visible, but, what seems more important, it did not match the original
KSyntaxHighlighting’s Breeze Light theme. In the latter, when the cursor
is at one of two matching brackets, they get turned bold and their
background is set to #ffff00
. Make the Kate style match Breeze Light’s
behaviour.
Here are both styles in action, for comparison:
The first picture one is from GtkSourceView, the second one is from KSyntaxHighlighting. The cursor is visible in the same place in both cases.
