I agree. i think I can get clang-format closer to that "minimum set"
but it seems to require still a few more modifications upstream.
Regarding spaces in [], I analyzed the score and found it was not
consistent, but more of the time there were not spaces:
$ grep -r "\[[^[:space:]]" | wc
2615 17577 191765
$ grep -r "\[[[:space:]]" | wc
223 1509 16393
So that one is manageable. The situation with spaces after parentheses
is trickier. There is a preference by some to avoid spaces in the
nested parentheses of arithmetic/logic expressions. This seems to be
somewhat consistent, but it is also a bit complicated to detect the
difference between:
z = ( x + y )
z = ( x + (x + y) )
Not impossible, but also not really standard anywhere that I have seen.
