* Use `command` consistently, silence ShellCheckTom Ryder2018-12-171-1/+2
| | | | | | | | | | ShellCheck (SC2164) is upset about these `cd` commands where the return type isn't being checked, but they're all by design, as they're the last command in the function, and thereby constitute the function's return value implicitly. Otherwise, this commit changes the shrc.d and profile.d subfiles to use the `command` wrapper only where it's actually needed.
