text: hook up indenting and unindenting to the undo/redo code
...
This is modeled after the comment/uncomment code. Each line's
individual indent is saved in the string array of the undo
group structure.
This fixes http://savannah.gnu.org/bugs/?46860 .

undo: generalize update_comment_undo() into update_multiline_undo()
...
The function does not contain any comment-specific code, so it can
be used to handle any kind of multiline undo item.
Also, extend the undo group structure to contain an array of strings,
one for each line in the group. When indent/unindent is hooked up to
the undo/redo code, this will allow the latter to restore the exact
original indents.

text: move the indenting of a single line into its own function
...
This is modeled after the undo/redo code for commenting. do_indent() now
calls indent_a_line() on each line it covers. The latter function will
eventually be used by the undo/redo code.

softwrap: improve left/right navigation across line boundaries
...
Using do_up() and do_end() when the user types <Left> at the start of
a line, and do_down() and do_home() when typing <Right> at line's end
can be problematic when tabs are wider than the screen, because those
functions convert indexes to columns and back again twice, thus causing
inaccuracies. Therefore, simply adjust current and current_x directly,
and then redraw the screen.

The preceding 'for' loop has already established that all the lines are

be unindented, it means it is fully blank, so it can be simply skipped.
