You simply never worked with cygwin under windows, nor transfered
files edited in windows to QNX et vice et versa.

It's not the desire of any one, it is just reallity. Simple modern
code editors (string editors) can deal with mixed line endings and
most tools won't care, this is just transparent, and we can have that
in Squeak to, it's easy and cheap.

For example, plenty of squeak code did contain line feeds, and that
did not hurt... (except when the ugly boxes were displayed).
If we have applications with strict requirements, then no problem, we
will continue to do the convert from/edit/convert to cycle.

Qui peut le plus peut le moins.
