I am all for (2) [*1*]
This and the previous "take a blank line as a hint" are both
heuristics. As long as the resulting code does not tax runtime
performance visibly and improves the resulting output 99% of the
time, there is no reason to leave end-users a knob. "Among 9 hunks
in this patch that touch hello.c, 7 are made much more readable but
2 are worse" cannot even be helped with a command line option.
[Footnote]
*1* I am also strongly against (3), if only to teach people a
lesson ;-).
