* P->style(type: beginning, style italic) -> o -> style(type:end, style:
* italic). But for this list to be coherent, it is mandatory that it is

* a file, so that the structure in memory is coherent. It makes input
* modules more comple, but output modules muche more simpler. The last
* particularity is that center must also be determined in the input
* modules, so that it is already defined in memory. But it is a bit more
* complex, because for TeX-like output modules, we need to close all
* styles before the center style: if the user types <i>pot</i> it must be
* represented as <i>p</i>{<i>o</i>}<i>t</i>.
*
* Here is the declaration of the gregorio_style struct. It is simply two
* chars, one telling the type of style character it is (beginning for a

* marking the end of a style). The other char simply is the style
