Sorry for the very late reaction.
Thanks for your contributions, excellent work!
For PmWiki 2.2.108 I have added a $PCCFOverrideFunction variable that
allows an addon to replace PCCF() with a custom function.
ChuckG already wrote such an addon here:
https://www.pmwiki.org/wiki/Cookbook/PccfToPcfOverride
For PmWiki 2.2.109 (already committed to Subversion) I have added the
$EnableMarkupDiag and $tracelev variables suggested by Chuck that allow
to backtrace all Markup() calls in ?action=ruleset, not only the
deprecated ones.
Thanks,
Petko

My Web host, 1and1, is running PHP Version 7.2.0RC6. I've updated
pmwiki.php to cause fewer "deprecated" warnings about Cookbook
recipes, and to provide some diagnostic information. Please see the
attached patch "pmwiki-cg.diff".
The first hunk defines two new functions:
1. PCF($args, $code) is a replacement for PHP's create_function(). It
creates a lambda function. When enabled by setting $EnablePCF to a
true value in a config file, it uses PHP eval() to create the
function. If not enabled, it uses create_function().
2. PCFWarn() is a utility function used by PCF and the modified PCCF.
When enabled by setting $EnablePCFWarn to a true value in a config
file, it adds an entry to the $MessagesFmt array describing the
function which was called (Markup_e, PPRE, PCCF or PCF), the name of
the file containing the call, the line number in the file and whether
a function had to be created.
It also modifies PCCF to call PCF instead of create_function and to
call PCFWarn if it gets the lambda from its cache array,
$CallbackFunctions.
The second hunk modifies the Markup and Markup_e functions so that, if
enabled by setting $EnableMarkupDiag to a true value in a config file,
the caller's file name, line number and pattern are saved in the
markup table for every call, not just those using the deprecated "e"
flag. This makes the ruleset and ruletable actions very instructive.
