Allow defining Before or After code in the config

[tkiselev]

I feel like this would be a useful feature. My specific use case is that I want to use pypyp with other *nix tools, but it often complains about broken pipes if I use commands like head.

One fix could be to add alias pyp='pyp -b "signal.signal(signal.SIGPIPE,signal.SIG_DFL)"' (see here) to my shell config, but I feel like it would be cleaner if I could set that in the configuration.

Thanks!

Thanks for mentioning!

I think it probably makes sense to just reset the SIGPIPE handler by default: #38

I could also provide the feature as requested: #39

Any thoughts of which one or both we should do?

Resetting the handler by default seems like a good idea to me, I don't have another specific use case for setting code in the config but it seems like a nice-to-have.
