How to reproduce:
1. Open or create a new Unity project
2. Import the attached script "PrefabUtility" and open it with Visual Studio
3. Right click on the method "PrefabUtility.SaveAsPrefabAssetAndConnect" and then click "Go to definition"
4. Click the plus which is left of the method to show the description

Expected result: Method description is clean and understandable
Actual result: Multiple typos ("childen", "same make") and make the method hard to understand

Reproducible in: 2018.3.0b2, 2019.1.0a1
Method was introduced in 2018.3

Note: Most likely, the word "time" is missing in the second typo, between "same" and "make".
