Replace all instances of err.strerror with err.

jeremyhylton · jeremyhylton · commit eaa6e3c71235 · 2001-10-08T20:33:20.000Z
The strerror attribute contained only partial information about the
exception and produced some very confusing error messages.  By passing
err (the exception object itself) and letting it convert itself to a
string, the error messages are better.
