The indentation should not have any effect on reloading a file, so a 
long pause is unexpected there.

In case you are running a version built on AppVeyor: there is a 
difference to a normal release in that it uses a stock dmd compiler. The 
official releases use a D runtime with a precise GC that can have a 
large impact on memory consumption. If you are editing large files this 
can make quite a difference.
