diffViewers parameters seem to be ignored

[dtimms]

I've customised slightly as I want diff to be run as: diff --unified=0 --report-identical-files

It seems these extra parameters aren't acted on (and I don't understand lamda..). I also tried kdiff3 selection and it seems also that it's parameters: kdiff3 --cs WordWrap=1 --cs ShowWhiteSpaceCharacters=0 may not be getting passed when view_diff runs:

• print "[%s]" % prg cmd = "%s "%s" "%s"" % (prg,fleft.name,fright.name) out = commands.getoutput(cmd)
