Indeed. But does it really matter ? We're in a case where there's a  
problem already...

Not a bad idea. Another option would be to give the user the  
possibility to skip the offending lines:
* we already know what number of columns to expect (nbcols)
* we check whether the current row has the correct nb of columns
* if it doesn't match, we skip or raise an exception with the  
corresponding line number. But even if we skip, we need to log the the  
line number to tell the user that there was a problem (issuing a  
warning ?)
