My goal is to put a line of text back to a text file (or back to a buffer that
get its data from a text file, but I don't know if such class exists). I'm parsing 
a file on a line basis, which makes the parsing code quite elegant. The problem 
is that I only know I have to stop parsing (temporarily) when I get a line
starting with a specific character. However this line has to be read again later.
That's why I used ungetch.

Michael.
