"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.
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."
A numeric prefix argument specifies a column: indent each line to that column.
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."
