Do not modify indentation if there's nothing to modify
The older code has been always deleting the whitespace, even if
indentation is already as expected. Fix that by replacing `indent-to`
with `indent-line-to` which avoids modifying the line if there's
nothing to modify.
As a bonus, this simplifies the code.
