Incorrect reporting of core update status

[fdiebel]

What type of report is this:

Q	A
Bug report?
Feature request?
Enhancement?

Description:

Since core update success is being check by grepping for version it throws an error when there is PHP log output like that below. Need to design a new way to check, comparing version numbers directly would be best.

If a bug:

Q	A
Deploy version	3.7.2-dev

Log errors:

Please check for related errors in your log files.

Difficult to track down, depends on so much environment stuff + wp-cli. Removing from milestone.
