[cvsspam-devel] diffs not character safe

[Elan Ruusamäe]

appears that when passed --charset utf-8 to collect_diffs the diffs are not 
characterwise but bytewise

and as cvsspamm appears to make diffs on same line coloured darker, it breaks 
multibytes

so if the diff would be:
-	'map_tab_label'			=> 'карта',
+	'map_tab_label'			=> 'Карта',

cvsspam hilights after first byte of letter 'k' because it's unicode first 
part is the same byte.

i've attached the mail fragment as i it can't be displayed properly in this 
utf8-encoded email.
