whitespace. Tabs are non-standard across systems and of a non-unit length and so when custom continuation lines are indented, they have to use a mix which wreaks havoc when the tab length goes from 4 to say 8 or vice versa. If you are interested in re-indenting code, then use a program/command that is actually designed for code re-indentation, not some inaccurate stupid shortcut like tab length manipulation. Pretty much any modern IDE would have a code re-indentation infrastructure.
