But what if there are cases where I *do* want quotes?

I'm more in favor of being as literal as possible. What you type for
the shell_build_command will be directly launched. This provides
greater flexiblity for if you *do* need quotes. For example:

shell_build_command = ./configure "CFLAGS=-g -O"

In this case you definitely do not want to remove the quotes.

More specifically, proper quoting handling is a really, really tricky
task and I don't really want to tackle it. :-)
