this is what i am getting:

Code:

$ ./x5
echo "flag is $-"
+ echo flag is vxh
flag is vxh
$ cat x5
#!/usr/bin/ksh
set -vx
echo "flag is $-"

with your input, I am getting:

Code:

$ ./x5
echo "flag is $-"
flag is vh
$ cat x5
#!/usr/bin/sh
set -v
echo "flag is $-"

I think "h" occurs in all cases. I am not sure for what "h" stands for.

       int echo(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.
