using -w with --before can trigger an infinite loop

[XertroV]

My setup atm requires generation of boilerplate-ish purs files

The problem is that using --before to generate these changes the source tree, which triggers the build process to restart, which triggers the --before script, .... and so on.

Since we don't have template-purescript it seems like this is going to be an issue for a little while at least.

I've also tried using -I to include a src directory outside my main one, but this doesn't help.

Any workaround ideas would be appreciated - I don't really want to give up using -w
