The regular expression that works for me in Find is:

The intention is to match an end statement with the same leading
whitespace as the function line.
But putting it into lua.plist (substituting < and > for < and

Fritz,
I've logged a bug against the documentation so this is made clear in
the future.
You are running into the following problem. The function pattern used
to scan for functions is based on your pattern. (It also combines the
string, comment and skip patterns.) Since you don't know how they
patterns are combined (and if you did, shouldn't rely on it is an
implementation detail which may change if necessary) you can't use
positional backreferences within your pattern.
The solution is to use named backreferences:
<key>Function Pattern</key>
<string>(?s)^(?P<leading_indent>[ \t]*)function\s+(?
P<function_name>[A-Za-z_:.]+).+?\r(?P=leading_indent)end\b</
string>
