Subject: Fixup b321bb1a: set changebar when inset contains changes
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=53196320e7b5034f13387e72cf706a019f8e9338;p=features.git

Fixup b321bb1a: set changebar when inset contains changes

Add Paragraph::isChanged() and InetText::isCgchanged() which indicate
the presence of a change in the relevant object.

Sets Row::needsChangebar() when adding an inset that contains changes.

Related to bug #8645.
