In r31258 [1], the output for limit=max was changed. The previous
implementation returned
<limits limit="500" />
when limit=max was used. However, a request like
api.php?action=query&list=logevents&prop=revisions&lelimit=max&rvlimit=max&rvprop=content&titles=Foo
caused the following problems:
* The code would try to overwrite the already set <limits> tag, causing
a fatal error
* prop=revisions&rvprop=content enforces a stricter limit (200) than
list=logevents (500)
These issues have been resolved by changing the output format to:
<limits logevents="500" revisions="200" />
This change is expected to be included in the upcoming 1.12 release
(unless Brion throws it out).
