It would be nice to have some user control - I find the first 100
characters or so is usually sufficient, especially when the real
problem is further down the stack. It is a real pain when you have
used do.call with a 10,000 row dataframe - and then it is basically
impossible to find the problem by manual inspection anyway. Even
limiting to 1000 characters would be a big improvement.
