Documentation

If non-nil Auto-Revert Mode reliably updates version control info.

Auto-Revert Mode updates version control info whenever the buffer needs reverting, regardless of the value of this variable. However, the version control state can change without changes to the work file. If the change is made from the current Emacs session, all info is updated. But if, for instance, a new version is checked in from outside the current Emacs session, the version control number in the mode line, as well as other version control related information, may not be properly updated. If you are worried about this, set this variable to a non-nil value.

This currently works by automatically updating the version control info every auto-revert-interval seconds. Nevertheless, it should not cause excessive CPU usage on a reasonably fast machine, if it does not apply to too many version controlled buffers. CPU usage depends on the version control system.

This variable was added, or its default value changed, in Emacs 22.1.

Probably introduced at or before Emacs version 22.1.
