+Subject: [PATCH] This patch allows to add spare font besides default. Some
+ glyphs can be not present in default font. For this glyphs st uses
+ font-config and try to find them in font cache first. This patch append fonts
+ defined in font2 variable to the beginning of font cache. So they will be
+ used first for glyphs that absent in default font.
