Steps to reproduce:
1. Start a fresh version of xwiki and go to http://localhost:8080/xwiki/bin/view/Main/
2. Edit the page in some way and save
3. Show the page history and compare the two versions (displayed as 1.1 and 1.2)
"From Version 1.1 To 1.2" (Or 1.14 To 1.15 if you imported with preserveVersion)
"From Version 1.1 To 1.16"
Note 1: In the XAR Main.WebHome has version 1.14
Note 2: Tried this with various files in the default wiki and panels api and they all exhibit this problem. The displayed version number for version 1.2 is always equal to the version number in the XAR + 2. The number for version 1.3 is always equal to the version number in the XAR + 3, etc.
