Updated the 'checking for ignorable lines'

Hi!

I modified the 'check for wildcard' to check at specifically the 4th column.
I found the suggestions from the mailing list realistic; if a line were to be a correction, there would be no space between the new word and the asterisk.

I welcome any further comments in this regard
