Why not use Perl?

$ perl -p0e '$_=~s/(.)\n(.)/$1 $2/g' < 1.txt
This is a test file, what I am trying to do is get the lines to join.

It isn't a complicated thing, but I also want to keep the paragraphs separate.

$ perl -p0e '$_=~s/(.)\n(.|\n)/$1 $2/g;$_=~s/ \n/\n/g' < 1.txt
This is a test file, what I am trying to do is get the lines to join.
It isn't a complicated thing, but I also want to keep the paragraphs separate.
