golines does not shorten index expressions in declarations #128
Description
golines will shorten a declaration like this:
foo := longlistfunc(bigarg, otherbigarg, verylongarg, veryverylongarg, veryveryverylongarg, extremelylongarg)to
foo := longlistfunc(
bigarg,
otherbigarg,
verylongarg,
veryverylongarg,
veryveryverylongarg,
extremelylongarg,
)I would expect it to similarly shorten a declaration like
foo := longlistfunc(bigarg, otherbigarg, verylongarg, veryverylongarg, veryveryverylongarg, extremelylongarg)[0]to
foo := longlistfunc(
bigarg,
otherbigarg,
verylongarg,
veryverylongarg,
veryveryverylongarg,
extremelylongarg,
)[0]
but it is left alone. This appears to be due to formatExpr not supporting index expressions. It results in a debug message like
Got an expression type that can't be shortened: *dst.IndexExpr
