There will be only one check in 9.4, so this sentence is confusing and should be reformulated.
Thanks, yeah I left that sentence unchanged from original patch, maybe I should remove the word "number" there as it implies that there are a lot of them, but I don't really want to change everything to singular when the input is specified as list.
What about add sentence: in this moment only "shadowed-variables" is available?
There is something like that said 2 paragraphs down the line:
+ The default is <literal>"none"</>. Currently the list of available checks
+ includes only one:
+ <variablelist>
+ <varlistentry>
+ <term><varname>shadowed-variables</varname></term>
