,----[ C-h f indent-relative RET ]
| indent-relative is an interactive compiled Lisp function in `indent.el'.
|
| (indent-relative &optional unindented-ok)
|
| Space out to under next indent point in previous nonblank line.
| An indent point is a non-whitespace character following whitespace.
| The following line shows the indentation points in this line.
|     ^         ^    ^     ^   ^           ^      ^  ^    ^
| If the previous nonblank line has no indent points beyond the
| column point starts at, `tab-to-tab-stop' is done instead, unless
| this command is invoked with a numeric argument, in which case it
| does nothing.
|
| See also `indent-relative-maybe'.
