@nimish13 Avoid fixing indentation issues if there's no code change as it makes tracking of code history difficult.

@Tanmay I feel fixing indentation is equally important as fixing a bug.
There may be a case where there is no optimization/fix in the code and in that case if there is some indentation issue that will never be fixed and it may make code look unpresentable.What is your thought about that?

@nimish13 I would prefer to have commit history correct over the presentation. In case indentation needs to be fixed, I would prefer to have a single fix throughout the code rather than having 1000 commits separately. Though I'm against fixing indentations until there's a code change.
