But the disadvantage is that you don't immediately see whether it is "and", "or" or something else.

That's why in most programming languages the coding style says you should put the operators at start of line instead of end of line, e.g.

GOOD:

    if ((...some_condition_that_may_make_sense...)
        && (...some_other_condition...)
        && (...and_yet_some_condition_that_makes_sense...))

    x = ((some expresssion)
         + (some other expression of different length)
         - (some final expression))

BAD:

    if ((...some_condition_that_may_make_sense...) &&
        (...some_other_condition...) &&
        (...and_yet_some_condition_that_makes_sense...))

    x = ((some expresssion) +
         (some other expression of different length) -
         (some final expression))
