Forums Feature Suggestions breaking /filter -k

I'd like to be able to break the filter -k call by doing something from the custom alias called (calling /return, probably).
Suprisingly, even /halt doesn't do anything:
This will halt because echo -a fails on empty line, and /filter was changed to halt if the custom alias throws an error (no problem with this)

So, maybe /halt not halting is a bug here, but in any case I think we should be able to break from /filter without breaking a loop or halting the current execution.

An example? Well let's suppose you have an INI file and you want to load a whole section to a custom @window, but you need to modify the actual output line, you can use filter with -r to start matching at the line where the section starts, and keep matching until you find an empty line, I could theorically use the above with :error to halt and hide the error but that doesn't seem like a good practice/idea.

I came across this thread https://forums.mirc.com/ubbthreads.php/topics/164216//filter_addition#Post164216n which itself links to this https://forums.mirc.com/ubbthreads.php?ubb=showflat&Number=144263&site_id=1#import

/halt should really be halting the whole execution/scope while /stopfilter or /filter -h would break the current /filter.

Bit of a bump.

Since $findfile and $hfind are not halting the whole script execution when /halt is used inside the command parameter, only the $findfile/$hfind, maybe it is consistent that /halt inside the callback alias of /filter does not halt the whole script execution.

But I really want to be able to stop a /filter -k from the alias.

More importantly:
While being able to stop the internal reading of the file would be great, it's clearly not possible as mentioned, something like /filter -h would only stop the loop on the cached lines, which would still be much faster than any other workaround.

Edit: of course -h is used now, any letter would do.
