As I have access to commercial Gerber Tool at work, I recently did some 
tests for importing diffrent Excellon format precision into GerbView:
7+8 digit formats (seems possible but no standard (???) and) are not 
detected automatically by GerbView. 6 digit formats 3.3 or 2.4 or 4.2 
always import correct with or without leading zero supression or 
step&repeat. Another thing I found, that the (old header) G81 FMT1 
instruction generates error message while G05 FMT2 equivalent does not 
(but both behave well). If anybody is interested in test file data I can 
dig for them or generate new test files
