Say you had to increase the level of indentation by one level. Source control program like Git will mark all lines within the block as changed. However, if you just modify the indentation level symbols, then those lines won't get marked as modified. Combine this with an intelligent editor which will automatically parse and visualize indentation symbols without actually adding whitespace in the buffer, as well as a simple key combination and script to facilitate quick un/indentation, and you would probably use fewer keystrokes than adding in braces everywhere.
