This is similar to sq_dequote_to_argv, but more convenient
if you have an argv_array. It's tempting to just feed the
components of the argv_array to sq_dequote_to_argv instead,
but:
1. It wouldn't maintain the NULL-termination invariant
of argv_array.
2. It doesn't match the memory ownership policy of
argv_array (in which each component is free-able, not a
pointer into a separate buffer).

* single quote pair.
|
|

|
|
* For example, if you are passing the result to system() as an
|
|
* argument:
|
|
*
|
|
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))

* would be appropriate. If the system() is going to call ssh to

|
* run the command on the other side:
|
|
*
|
|
* sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1));
|

* sq_quote() in a real application.
|

|
|
* sq_quote_buf() writes to an existing buffer of specified size; it
|
|
* will return the number of characters that would have been written
|
|
* excluding the final null regardless of the buffer size.
