In Emacs, I have commands defined to adjust the indentation of the
selected region. Surely any other decent editor would offer the same.
Writing editor editor macros in order to work around fundamentally bad
language design is not something a programmer should have to waste
time on.

block of code is to select the lines, then press "Tab". Unindenting
is "shift-Tab". Changing tabs to spaces or spaces to tabs is done
by selecting "Tabs to spaces" from the Edit menu, or something
equally simple and obvious. Many editor can be set to convert tabs
to spaces (or vice versa) when saving files, perhaps specific to the
file type (so you don't muck up your makefiles).
It takes a special kind of genius to be able to program, and yet
still have trouble with this kind of thing.
The main problem isn't in changing the indentation of a block of code;
it is in HAVING to do so because of poor language design. A lesser one
is having to rely on whatever varied features that 100s of different
editors may have to do so.

And yet another, of more significance, if that after you've indented a
block, it may now merge into an adjacent block that was already at
that new indent. If you later need to revert that first block back to
it's original position, you'd better make sure you mark that boundary.

It is a language design issue pure and simple. Don't try and pin it on
the users and make out it's due to lack of expertise with their
editors. Of course we can all indent blocks; it's just an unnecessary
palaver.

Clearly your point of view is as a language /user/ where languages and

about, can't change, and need to work around.

But some of us devise (and, importanly, implement) languages of our

scope to another, I can get away with leaving the indentation as it is,
because all the compiler cares about is where the braces are. But I
*always* adjust the indentation to fit the code's new context.
Python's use of indentation to indicate scoping just means that I have
to do what I would have done anyway.
