<Plug>(operator-sandwich-replace) is slow in large files

[infokiller]

Thanks for the great plugin!

I'm using the following mapping:

nmap srr <Plug>(operator-sandwich-replace)<Plug>(textobj-sandwich-auto-a)

This works well in files with less than ~1000 lines, but there's a large delay in files with a few thousand lines. The problem seems to be <Plug>(operator-sandwich-replace), since if I try call feedkeys("\<Plug>(textobj-sandwich-auto-a)", 'm') it works fast enough, and if I try call feedkeys("\<Plug>(operator-sandwich-replace)ab*", 'm') (with plugin mappings turned off) it works

<Plug>(operator-sandwich-delete) works much faster.
