Has there been a continuous debate over the years, if the source code lines were returned using tabular or spatial characters? In general, most people do not bother to read code that is consistently returned by tabs, or in code that is consistently entered using spaces. Complications occur when some of the lines are bled with the cards and others are bled with spaces. In these cases, the code will be displayed correctly if the reader has the same tab settings as the authors and all authors have used consistent patterns.

Which is most comfortable for you?
