Option to skip new version when updating text

I agree with this. I'm currently only in Dev, but I already have like 5 revisions from just toying with it.

Here's a janky patch that includes stuff from (and requires the patch from) #226117: Input filters support but gets things moving.

+          'changes' => $values['changes'],
+      ))
+        ->condition('version', $version['version'], '=')
+        ->condition('revision', $version['revision'], '=')
+        ->execute();
+    }
 

So this will silently overwrite the last revision with whatever was entered, thereby dropping revision safety / traceability of changes?

I see major objections with this.

Imho the approach should be
* to always save new revisins, but mark some revisions as non-substantial
* filter them out in legal_get_conditions()
* change legal_version_check() to >=
