======Synopsis:======
[[set]] indent [on|off|toggle]

======Description:======
When turned on, long lines will be wrapped such that they are indented
to the same position as the second word on the first line.  Subsequent
wrapping of the same line will be indented to the same place.

If [[set CONTINUED_LINE|CONTINUED_LINE]] is also set, the client will pad the
wrapped portions of the line with the [[set CONTINUED_LINE|CONTINUED_LINE]]
contents, unless [[set CONTINUED_LINE|CONTINUED_LINE]] happens to be longer
than the indented space.  [[set CONTINUED_LINE|CONTINUED_LINE]] will not be
truncated in this event; it is either displayed in full, or not at all.

The client will never indent a line more than one-third the width of
the screen when __INDENT__ is enabled.
