[PATCH/RFC] Documentation/git-mailsplit.txt: Emphasize -o more

[jidanni@jidanni.org]

The need for -o cannot be overstated. Else the arguments get
interpreted differently. We also mention the output.
(By the way, "fatal: unknown option: -o" is seen if a space comes
after it.)

 -----------
 Splits a mbox file or a Maildir into a list of files: "0001" "0002" ..  in the
 specified directory so you can process them further from there.
+The number of files produced is printed to the standard output.
 
 IMPORTANT: Maildir splitting relies upon filenames being sorted to output
 patches in the correct order.
