Eugene Sandulenko 11a17b3908 SCUMM: Fix subtitles for Russian The Dig 
It is a long standing bug which was revealed by r31784. With that commit
Kirben switched DIG code to newer one. Russian version used 0x03 as
placeholders for keeping string widths. Original did not copy those
characters but we did hence the bug. Based on study of original.

Restrict it to Dig-only in order to avoid regressions.
