vim line wrap with indent

UPDATE: This functionality landed in vim 7.4.338, though you'll want 7.4.354 or later.

So apparently this requires a patch to Vim. There is a patch by Vaclav Smilauer from back in 2007. I updated the patch to work with Vim 7.2.148 from Fedora 11. But it does seem to do the job.

In your .vimrc:

set wrap               " soft-wrap lines

" requires +linebreak compile-time option (not in the 'tiny' and 'small' builds); check your :version
set showbreak=----->   " prefix for soft-wrapped lines (no actual line break character)
"set linebreak          " soft-wrap lines only at certain characters (see :help breakat)

" If you like line numbers, you may want this instead:
"set number
"set showbreak=------>\  " line up soft-wrap prefix with the line numbers
"set cpoptions+=n        " start soft-wrap lines (and any prefix) in the line-number area

Or just type :set showbreak=-----> in any session.

For reference, my research trail (Vim 6.2): :help 'wrap' -> :help 'linebreak' -> ( :help 'showbreak' -> :help 'cpoptions', :help 'breakat')

The solution to your question can be achieved setting two parameters in your vimrc:

To break the lines with the same indentation: set breakindent

And one space for indenting soft-wrapped lines: let &showbreak=' '

It will work this way:
