[BUG] double-use of short option "-s" in textDump module

Executive summary:
'-s' short option is used for two different flags for
the textDump command arguments, causing confusion and
much consternation for Tim.

Long story:
I can't believe it bit me again!  I reported having problems
with using the textDump module to output stats in August,
and Robert Wisniewski helped me out by telling me to use the
"--stats" option.  Back then, I never did figure out why
using the "-s" option didn't have the desired effect.

I've been working on other stuff, and got back to working
with lttv. (an older version (0.8.46), sorry), and I tried to
use the "-s" option to get stats again.  For the life of
me I couldn't figure out why I was successfully getting
stats in the gui but not from textDump.

In a forehead-slapping moment, I discovered this sequence
in the textDump online help:

...
> --stats  -s  argument:
>                      write the traceset and trace statistics
> --output  -o  argument: file name
>                      output file where the text is written
> --field_names  -l  argument:
>                      write the field names for each event
> --process_state  -s  argument:
>                      write the pid and state for each event

It looks like textDump uses the short option '-s' for
BOTH --stats and --process_state.  Upon more careful review
of my output, I was, indeed, getting the process_state
in my event output.  I missed it because I kept looking
at the stats stuff and not the event lines.

Has this been fixed in a more recent LTTV?  Can we change
one of these short options to something else to avoid this
confusion in the future?  I'll be happy to submit a patch
if someone will express a preference for the option letter.

Thanks,
 -- Tim
