Don't print extra newlines on error before awk starts parsing. (#97)

Browse Source 
If awk prints an error message while when compile_time is still set
to ERROR_PRINTING, don't try to print the context since there is
none.  This can happen due to a problem with, e.g., unknown command
line options.
