When sage converts a long list to a latex string, it inserts '\\' as a
separator. Is this desired behavior? In many tex situations this does
nothing, and in other situations it causes problems. To me, it seems
that the only situation where this behavior is desired is covered by
EMBEDDED_MODE (whatever that is) which wraps the list with an array
environment.
If this is not the desired behavior, perhaps I will submit a patch to
fix it, or else, since the change is just one line, perhaps I might just
leave it by saying:
Changing line 67 of sage/misc/latex.py (in function list_function(x))
from
sep = ', \n\\\\'
to
sep = ', \n '
solves the problem, if this is indeed a problem.
An example follows:
sage: a = [1/2 for i in range(20)]
sage: latex(a)
\left[\frac{1}{2},
\\\frac{1}{2},
\\\frac{1}{2},
\\\frac{1}{2},
\\\frac{1}{2},
\\\frac{1}{2},
\\\frac{1}{2},

\\\frac{1}{2},
\\\frac{1}{2},
\\\frac{1}{2},

sage: sage.misc.latex.EMBEDDED_MODE=True
sage: latex(a)

\end{array}
