"Indent each nonblank line in the region.
With no prefix argument, indent each line using `indent-according-to-mode',
or use `indent-region-function' to do the whole region if that's non-nil.
If there is a fill prefix, make each line start with the fill prefix.
With argument COLUMN, indent each line to that column.
A numeric prefix argument specifies a column: indent each line to that column.
When you call this from a program, START and END specify
the region to indent, and COLUMN specifies the indentation column.
If COLUMN is nil, then indent each line according to the mode."
With no prefix argument, the command chooses one of these methods and
indents all the lines with it:
1) If `fill-prefix' is non-nil, insert `fill-prefix' at the
beginning of each line in the region that does not already begin
with it.
2) If `indent-region-function' is non-nil, call that function
to indent the region.
3) Indent each line as specified by the variable `indent-line-function'.
Called from a program, START and END specify the region to indent.
If the third argument COLUMN is an integer, it specifies the
column to indent to; if it is nil, use one of the three methods above."
