It may be valid, some projects use tabs for indentation and spaces
for alignment, e.g.:

	if (cond && (cond1 ||
	             cond2))
		...

The second line is actually:
	             cond2))
<TAB--->SSSSSSSSSSSSScond2))
where 'S' means space.

This is the only way to write code which display correctly with
different tab sizes.

With tab = 4 spaces it would be expanded to:
    if (cond && (cond1 ||
                 cond2))
        ...
I.e., it would be still fine.


Most of the formating tools probably can't do it automatically.
