I use gb4e for formatting linguistic examples. I came to an example in which I want to show that one translation is correct and another reading is not allowed. I'd like to indicate that the second translation is bad by placing a raised asterisk before it. gb4e provides a way to align the left-edge vertically when an asterisk is placed in front of the first line (to indicate that the example itself is ungrammatical). Is there a way to align the left-edge when an asterisk is put on the second translation line (the \glt line)?
A MWE is as follows (I'm using xelatex):
\documentclass{article}
\usepackage{fontspec,xunicode}
\usepackage{gb4e}
\begin{document}
\begin{exe}
\ex
\gll bites dog cat\\
verb dd cc\\
\glt `The dog bites the cat.'\\
$^*$`The cat bites the dog.'
\end{exe}
\end{document}
