Hi Luc,
That's a bizarre bug!
One way to avoid these kinds of errors is to use the \[IndentingNewLine]
(the alias is esc n l esc) instead of Return. Then Mathematica will
keep track of delimiters and indent the amount appropriate for the
number of open delimiters. The option LineIndent controls the amount of
indentation.
With this method of input, you'll find out immediately that you have
left out a quote, because the subsequent lines will immediately indent
to the right when you type an open quote, and indent to the left when
you type a close quote. However, this didn't completely solve the
problem, because after I fixed up the text, the closing bracket ] of
the Module was still indented to the right too much. This at least let
me know that I shouldn't evaluate the cell, since there was something
wrong with the delimiter matching. When I deleted the closing bracket
and retyped it, the indentation of the module looked correct, and
evaluated correctly.
So, why don't you change the option LineSpacing to 3 or something and
try using \[IndentingNewLine] instead of Return.
Good luck
