Needs a whitespace fix.

IMO, we shouldn't suggest run(`sh -c "..."`) as a "workaround" to not having native piping/IO redirection in cmd literals and instead directly insert e.g. run(pipeline(`ls`, "out.txt")) here. It's safer, as it doesn't go through a shell for actual shell evaluation, thereby losing safety advantages granted by cmd literals in the first place.

It's not suggested as a "workaround" (that word is not used!). The FAQ entry heavily recommends using pipeline and Glob.jl, and emphasizes the downsides of the shell. But I think it's also important to say that sh -c "..." is what functions like os.system("...") are really doing in other languages, and of course you can do that too in Julia if you want.

But I'll edit it to include the Julia-native version.
