Claerd conflicts with my own #1621. (His was easy. :-) )

corrected typo in fonts/README.fonts

Applied changes to the new delta-configurations
 and deletet there some extra whitespace at the line-endings.

+/*
+This is a feature to protect your printer from burn up in flames if it has
+a thermistor coming off place (this happened to a friend of mine recently and
+motivated me writing this feature).
+
+The issue: If a thermistor come off, it will read a lower temperature than actual.
+The system will turn the heater on forever, burning up the filament and anything
+else around.
+
+After the temperature reaches the target for the first time, this feature will
+start measuring for how long the current temperature stays below the target
+minus _HYSTERESIS (set_temperature - THERMAL_RUNAWAY_PROTECTION_HYSTERESIS).
+
+If it stays longer than _PERIOD, it means the thermistor temperature
+cannot catch up with the target, so something *may be* wrong. Then, to be on the
+safe side, the system will he halt.
+
+Bear in mind the count down will just start AFTER the first time the
+thermistor temperature is over the target, so you will have no problem if
+your extruder heater takes 2 minutes to hit the target on heating.

Marlin/fonts/README.fonts

 The fonts are created with Fony.exe (http://hukka.ncn.fi/?fony) because Fontforge didn't do what I want (probably lack off experience). 
 In Fony export the fonts to bdf-format. Maybe another one can edit them with Fontforge.
 Then run make_fonts.bat what calls bdf2u8g.exe with the needed parameters to produce the .h files.
-The .h files must be edited to replace '#include "u8g.h"' with '#include <utility/u8g.h>', replace 'U8G_FONT_SECTION' with 'U8G_SECTION', inset '.progmem.' right behind the first '"' and moved to the main directory.

 Especially the Kana and Cyrillic fonts should be revised by someone who knows what he/she does. I am only a west-European with very little knowledge about this scripts.
