    Adjust backslash alignment syntax-check · d09429ab
    Martin Kletzander 提交于
    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.
