You really shouldn't have spaces, tabs, etc. before a paragraph break or a section break. You can clear out those spaces & tabs with a wildcard Find/Replace, where:
Find = [^t ]@([^13^12])
Replace = \1
You should generally also have paragraph breaks before Section breaks. You can ensure that with a wildcard Find/Replace, where:
Find = ([!^13])([^12])
Replace = \1^p\2
