I understand the question to be:
- some tools (group G) display program source code using
- some tools (group E) display program source code using
- without any reference to TAB characters,
- surely it is difficult to write neatly aligned files
that display reasonable in both sets of tools?
To which the answer is "yes, certainly."
That's why I classified the tools as G(ood) and E(vil).
If you don't care about lining things up in a tabular way
to reveal common structure, then "blind" group E tools may
work for you; you won't _have_ any alignment that you care
to preserve, so group G tools will also work for you.
If you want proportional fonts AND you want neat tabular
formats, then you need some kind of "smart" group E tool.
For example, you might want to write your code in
Microsoft Word -- don't laugh, I've known it done -- using
its facilities for managing tabulation, and have the code
automatically extracted from the text, using a "code" style
to mark the chunks you want.
In that case, of course, you don't greatly care about
alignment in the raw code, so don't worry about preserving it.
