I think the keyword value 'each-line' is misleading but I agree
'after-break' as proposed by HÃ¥kon[1] is not converying the right
intent either. What about 'each-paragraph'?

Fundamentally, I am not sure what use case this value is trying to
solve, and why isn't it solved by 'padding'. I treat it as a fix for
this case

  <div>
    <p>Some pargraph...</p>
    This is a new paragraph but it don't get 'text-indent' without
    this new value.
  </div>

, which is somewhat mysterious because before I read the spec and
tested it, I supposed the anoymous block would inherit 'text-indent'
from <div> per CSS2.1 but it does not...


(The rest is probably editorial but let's give the spec some
theoritcal rigor :)

  # The indent is treated as a margin applied to the start edge of
  # the line box.

This is somewhat ambiguous because it's not clear if the width of
the line box is calculated as either

  * A block-level box, where margin decreases the width.
  * A inine box, where the width is a constant.

We obviously want the first and not "shifted line box", and this
should be clarified.


I also think it would nice to specify that the 'width' of a line box
is determined by:

  * First, lay out floats and do the line box shortening.
  * Second, apply 'text-indent' for further shortening.
  * Thrid, push line box down and jump to first if no content.

Or otherwise, any ordering of the above seems to be allowed by the
current specs.

I haven't observed any incompability on this but I haven't tested IE and
Presto....
