On a serious note tho, I never understood the benefits of GNU's spaces after functions. I don't really mind most of the rest but I just don't get the benefits of 'funcname (arg)' vs. 'funcname(arg)'. Is there a specific reason for this? Personally, I find this to reduce readability because I have to think for a split second whether I'm looking at a variable or a function call.
Of cause this is also due to my habits, but I'm curious as to what the reasoning is.
Honestly I think it's just "spaces before open parens" and at least it's consistent. K&R, which I use, wants spaces before the parens in conditionals and loops but not in method sigs or method calls and the linter at work gets me almost every time I type the word "if".
Fair enough if the GNU dudes valued consistent spacing more than taking function calls as one "logical block". Not my cup of tea but that's what configurable auto formatting is for.
