    sh(1): Describe subshell environment, command substitution better
    
    POSIX does not require the shell to fork for a subshell environment, and
    we use that possibility in various ways (command substitutions with a
    single command and most subshells that are the final command of a shell
    process).  Therefore do not tie subshells to forking in the man page.
    
    Also, fix some sentences with excessive semicolons.
