I've got some sloppy text that needs to be cleaned up. Somehow random line breaks got inserted in the middle of paragraphs.

```
This is a paragraph
and it got broken into two lines.

```

The manual way to deal with this would be to 

1. Place my cursor at the beginning of line 2
2. Hit delete to bring that line up to line 1
3. Hit space to separate the two words that get mashed together by doing this

Is there a way to accomplish this with Find and Replace? I know I can find the offending lines with `^[a-z]` and checking "Case Sensitive", but that's as far as I can get.

I'm just starting to learn how powerful pattern matching can be and I've solved all the other cleanup issues, but this one still perplexes me.
