Description of problem:
The function ss_execute_line in execute_cmd.c contains the following code:

    /* parse it */
    argv = ss_parse(sci_idx, line_ptr, &argc);
    if (argc == 0)
        return 0;

Potentially we need to free argv before early return since it was allocated
memory. We need to be careful and check argv since it may be possible for
ss_parse() to have freed the memory allocated to it if it detects an unbalanced
set of quotes passed to it.

Version-Release number of selected component (if applicable):
e2fsprogs-1.35-12.4.EL4

How reproducible:
Not sure.

Steps to Reproduce:
Also tricky to reproduce this one. I'm not familiar with ss's internals to come
up with a test case that will clearly show this problem, but again the flaw is
fairly obvious.
  
Actual results:
ss_execute_line may fail to free resources allocated by it.

Expected results:
ss_execute_line correctly frees resources allocated by it.
