Adjust backslash alignment syntax-check
Adjust backslash alignment syntax-check

We have a check for backslash alignment that checks for two blanks preceding a
backslash.  However there can be alignment done using a tabulator and in some
cases one might be enough.  There are none currently, but I found out that was
the case before. at some point.  so let's check for \t preceding the final
backslash as well.
