Describe the bug

I've tried simple string substitution with this plugin, but it threw error messages below.

As a clue, it works fine if list of qf has a single path.

Error detected while processing BufWriteCmd Autocommands for "<buffer=17>":

I was able to repro this once but never after. I think I've found what the issue is, can you update and see if the problem goes away?

After last update #31, the problem went away like magic. Wonderful !!
