Not to switch off electric-indent, no (it's enabled globally).

And presumably the : was made to re-indent because in some/many cases
there is only 1 correct indentation (and the code is able to find it).
I don't know if the code is also able to detect when it's correct and
when it's not, but if it is, then we don't need to disable the "reindent
on :" in all cases.
