Slow #32

Hi,

I notice slowdowns by easytag when it autoupdates tags/highlights.

I enabled vbs=1 and observed that highlighting takes >4 seconds, while updating the tags takes ~2 seconds. However, running a simple ctags from the command line only takes ~ 0.01s, so I wonder where easytags wastes it's time...

Any idea?

I have tried some debugging. It seems that s:filter_merge_tags() is the culprit, which takes about 2 seconds in my case when updating a python file with 240 lines of code and using tag files separated by file type where the python tagfile is around 6000 lines.

Is this normal?
