fix redirection parsing sometimes skipping over redirections
This happens when multiple redirections are following each others, such as in
echo hi > out < in
which would be parsed as
╰─ t_cmdgroup
├─ t_cmdlist
│ ├─ num_cmds = 1
│ ╰─ cmd[0]
│ ├─ t_cmdlist_item
│ │ ╰─ t_pipeline
│ │ ├─ num_cmd = 1
│ │ ╰─ cmd[0]
│ │ ╰─ t_simple_cmd
│ │ ├─ words = [echo][hi][<][in]
│ │ ╰─ t_redir_list
│ │ ╰─ redirection[0]
│ │ ╰─ t_redirection
│ │ ├─ t_redir_type = REDIR_OUTPUT
│ │ ╰─ marker = [out]
│ ╰─ t_operator = END
╰─ (no redirections)
when the correct parsing is
╰─ t_cmdgroup
├─ t_cmdlist
│ ├─ num_cmds = 1
│ ╰─ cmd[0]
│ ├─ t_cmdlist_item
│ │ ╰─ t_pipeline
│ │ ├─ num_cmd = 1
│ │ ╰─ cmd[0]
│ │ ╰─ t_simple_cmd
│ │ ├─ words = [echo][hi]
│ │ ╰─ t_redir_list
│ │ ├─ redirection[0]
│ │ │ ╰─ t_redirection
│ │ │ ├─ t_redir_type = REDIR_OUTPUT
│ │ │ ╰─ marker = [out]
│ │ ╰─ redirection[1]
│ │ ╰─ t_redirection
│ │ ├─ t_redir_type = REDIR_INPUT
│ │ ╰─ marker = [in]
│ ╰─ t_operator = END
╰─ (no redirections)
