Supersedes the pervious one.

I discovered this bugs while implementing extract_font_range for allegrogl.

Basically:

first: inability to extract, e.g, range (50, 80) from font with two ranges, 
e.g., (30, 60) and (70, 90). With the fix, the now font in this case would have 
two ranges: (50, 60) and (70, 80).

second: passing -1 as the third argument to extract_font_range() would omit the 
last glyph

third: extract_font_range() would return NULL if you pass, e.g, 30, -1, because 
begin < end check at the beginning of the function would fail.
