Suppose autoindent is enabled and we have a line with an initial
tab where we want to split the words onto separate lines:
split the words
One way to do this is with the sequence 'f r<CR>;r<CR>', but in
BusyBox vi the result is:
split
he
words
This is a regression introduced by commit 9659a8db1 (vi: remove
autoindent from otherwise empty lines). The amount of indentation
is being recorded when the 'r' command inserts a newline but
isn't subsequently reset. A fix is to only record the indent
when in insert or replace mode. Proper handling of the 'o' and
'O' commands then requires them to switch to insert mode before
calling char_insert() to insert a newline.
