This is a simple plugin that requires a user to enter a comment when making changes to a wiki page.
Current version has some user configurable options:
|option name||type||default value|
|error_text||string||"A full comment must be supplied for this change,|
or use " <cosmetic_change_comment> " if no actual informational content has changed."
If you already use it, consider an upgrade before/when upgrading Trac from 0.11,
since there was a small bug hitting trac-0.12dev anywhere after r9284.
The fixed version was tested with trac-0.12dev-r9443 and works, but lacks i18n support introduced to Trac in this release.

Simply install the hack, sit back, and BE AMAZED.
