I have to edit lots of documents for consistency. Some authors use one space after a sentence and others use two. What is the easiest way to find (say) all occurrences of end-of-sentence punctuation that have only one space afterwards and replace the single space with two spaces? Of course, I don’t want to confuse periods in abbreviations with periods at the end of sentences if I can find an easy way to avoid it.
Any ideas? Thanks in advance.
