One simple example to illustrate what I mean, even assuming that the space is 
our word separator. What should be the file format of the latex paragraph?

The most famous equation of all times is $E=mc^2.$


How do we represent the space between "is" and the math inset?


Now we do (pardon me the markdown syntax :-) ):

``` lyx
\begin_layout Standard
The most famous equation of all times is 
\begin_inset Formula $E=mc^{2}.$
\end_inset


\end_layout
```

What would be the alternative? To have a space before the \begin_layout? That 
does not seem right and it would complicate our parsing a lot.

The option I am thinking, although a bit ugly, would be:

``` lyx
\begin_layout Standard
The most famous equation of all times is
\space
\begin_inset Formula $E=mc^{2}.$
\end_inset


\end_layout
```

That would mean that we have a special syntax for a line with a single space.
