format: introduce 'format.usegeneraldelta` This option will make repositories created as general delta by default but will not make Mercurial aggressively recompute deltas for all incoming bundle. Instead, the delta contained in the bundle will be used. This will allow us to start having general delta repositories created everywhere without triggering massive recomputation costs for all new clients cloning from old servers.

 ``format``
 ----------
 
+``usegeneraldelta``
+    Enable or disable the "generaldelta" repository format which improves
+    repository compression by allowing "revlog" to store delta against arbitrary
+    revision instead of the previous stored one. This provides significant
+    improvement for repositories with branches. Disabling this option ensures that
+    the on-disk format of newly created repository will be compatible with
+    Mercurial before version 1.9.

 ``usestore``
     Enable or disable the "store" repository format which improves
     compatibility with systems that fold case or otherwise mangle
