Eclim uses signs for code reference searches and they shows up as INFO
signs. These are not errors/warnings and hence should not be included in
count.
Testing:
Verified the right count shows up.
In large code base, typically there will lot of warnings because the
file has been changed by many people and not everyone bothered to follow
coding conventions. So its more useful to show the errors first. Once
all errors have been fixed, we can focus on warnings.
