Feature Request: Accept a custom prompt_parser #53
Description
I would like to have the ability to provide a custom prompt_parser to further customize this plugin. It'll be extra nice if the parser can return some extra arguments to be passed on to vimgrep_args
Example Use case:
I want to just type what i want into the field and not think about quotes and globs and break the flow when I'm in the middle of debugging something.
Here's my test implementation of prompt_parser. Probably buggy and misses some corner cases but I used it on a whole day of work and it seemed fine.
I'll add the ability to escape / and starting - in the future.
Maybe we can have this kind of 'quoteless mode' as a feature on the plugin.

I'm not sure if it's a good idea to do it like this, but just wanted to test the functionality, here's the PR: #52
