preserveLineBreaks but only if they are in pairs?

Apologies if this is a silly feature request, but we're working on converting some PDF and word documents. The PDF files seem to have line breaks in the middle of sentences (where they hit the edge of the page), while the word files do not. Both types of files have double (or paired) line breaks where there are paragraphs.

We'd really like to preserve the paragraphs, but eliminate the single line breaks. Would it make sense to have another option like preserveMultipleLineBreaks or something?

I've managed to achieve the effect that we would like by inserting the following:

text = text.replace(/(^|[^\n])\n(?!\n)/g, '$1');

prior to the following line in extract.js

text = text.replace( WHITELIST_PRESERVE_LINEBREAKS, ' ' );

so maybe a STRIP_ONLY_SINGLE_LINEBREAKS option to have this run before the WHITELIST_PRESERVE_LINEBREAKS operation ...

I could pop in a pull request if this made sense ...?

This isn't an outrageous ask. Probably going to run through another batch of tickets soon and get 2.3 out the door, I can toss this in.
