These filters may explain the problem that I see.
I would not mind being wrong...
I plan to put a bug report in Proxomitron Program later.

Add the filters to the top of your Web Page Filters.

Code:

[Patterns]
Name = "A -- correct: $TST(\0=*) does not match"
Active = FALSE
Limit = 256
Match = "$TST(\0=*)"
Replace = "\k"

Name = "B -- incorrect: $TST(\0=*) does match"
Active = FALSE
Limit = 256
Match = "(^z)\0nevermatch(^)|$TST(\0=*)"
Replace = "\k"

Name = "C -- correct: $TST(\0=*) does not match with workaround"
Active = FALSE
Limit = 256
Match = "(^z)(\0)nevermatch(^)|$TST(\0=*)"
Replace = "\k"

Name = "D -- Create problem for A and C "
Active = FALSE
Limit = 256
Match = "(^z)\0nevermatch(^)"
Replace = "\k"

Test filter "A". Test should fail because \0 should have no value.

Test filter "B". This filter should not match but does!
The left side of the match "(^z)\0nevermatch(^)" always fails. The right side is the same as filter "A"s match.
Filter "B" and filter "A" should test the same.

Test filter "C". Test should fail because \0 should have no value and does fail. Putting the variable in parentheses 'fixes' something.

Enable filter "A" and filter "D" and try to load Google. Google should load but will not!
Filter "D" never matches and should not change the value of the positional variable \0.
However, after filter "D" fails, filter "A" finds "$TST(\0=*)" to be true and matches.

If so, we'd also need a Perl-style RegEx that finds all such expressions (for Notepad++ or UltraEdit, must match nested parens).

I tend to agree with

I don't think the perfect expression is possible. Errors could be introduced.
