rc's Issues

Awesome Shell

This shell is awesome, but it's hard to work with lists. I can concatenate them, but can't remove members. It would help to have the shift builtin accept a variable name. Should I put in a PR for that?

Typo in README(?)

I wonder why the README suggests to define the auto-completion functions in .rcrc_ rather than .rcrc. My guess is because .rcrc_ contains a typo.

I'd also format both the file and the function name as code rather than using italics.

Unable to build under Arch Linux

make output

The linker fails as it reports hundreds of instances of macros being defined multiple times.
