Feature request: Option to include default message when log message is present

Problem/Motivation

When a revision log message is entered, the default log message is omitted.

Steps to reproduce

Leave the revision log message blank and the default revision log is used.

Enter any text into the revision log message and only that text is used. The default revision log text is omitted.

Proposed resolution

Create a configuration item to enable the default revision log message to be appended to any input revision log message.
