To the limited extent that I understand the distinction you are
making between "indentation" and "alignment", I don't understand it.
To me, indentation simply *is* "making some aspect of structure
directly visible by mapping nesting depth to distance from the
A 'character' which corresponds to an unpredictable and uncontrollable
amount of white space simply isn't up to the job. (Yes, if you put an
Emacs mode line into a file, tab width *is* predictable and controllable
for that file, BUT ONLY IN Emacs.) If you mean that the indentation
will be *logically* correct as far as a parser is concerned, fine.
But it won't be *visually* correct.
By the way, the IDE didn't, for all practical purposes, offer me any
choice in the matter.
