start_command() followed by finish_command(). Takes a pointer
to a `struct child_process` that specifies the details.

The caller:
-1. allocates and clears (memset(&chld, '0', sizeof(chld));) a
+1. allocates and clears (memset(&chld, 0, sizeof(chld));) a
struct child_process variable;
2. initializes the members;
3. calls start_command();
.no_stdin, .no_stdout, .no_stderr: The respective channel is
redirected to /dev/null.
- .stdout_to_stderr: stdout of the child is redirected to the
- parent's stderr (i.e. *not* to what .err or
- .no_stderr specify).
+ .stdout_to_stderr: stdout of the child is redirected to its
+ stderr. This happens after stderr is itself redirected.
+ So stdout will follow stderr to wherever it is
+ redirected.
To modify the environment of the sub-process, specify an array of
string pointers (NULL terminated) in .env:
. If the string is of the form "VAR=value", i.e. it contains '='
the variable is added to the child process's environment.
-. If the string does not contain '=', it names an environement
- variable that will be removed from the child process's envionment.
+. If the string does not contain '=', it names an environment
+ variable that will be removed from the child process's environment.
To specify a new initial working directory for the sub-process,
specify it in the .dir member.
