This small patch adds more error info to the .tcl command by
outputting $errorInfo to your idx.

It was made on a development version of 1.5, but should work 
on any version of 1.5 because the changes are so small, if not
it shouldn't be hard to patch src/cmds.c manually, you change
only 3-4 lines.
