That depends on your editor. SciTE, for instance, will give a warning
any time indentation changes wrongly; if you mix tabs and spaces,
there'll be error markers at the beginning of each change (so if
there's one line with eight spaces amid a sea of tabs, that line and
the one below it will be marked).
