Source code and terminal windows are probably the last bastions of fixed-width 
fonts, and given the overt use of white space in code styling, I think we can 
expect it to remain that way for the forseeable future.  Maintaining the 
two-space separation helps in a number of ways, not least making it more clear 
when a period (full stop) is used for non-sentence ending punctuation, it's 
not ending a sentence -- e.g., in numbers lists, and even the "E.g.," earlier 
in this sentence. :-)  Perhaps we should add a bit more information on comment 
formatting to style(9) and include this point.
