...<command> argument (but still resolve tilde). This makes it easier to write sh -c '' constructs without turning labwc into a shell parser in order to expand environment variables, whilst respecting single quotes and escaped characters as well as ignoring subshells syntax like $(foo) and backticks. Also, fix bug where buffer length+alloc get out-of-sync
