That's an interesting question. I guess the /maximum/ number of underscores would be something in the area of 10. Most have between two and four.
I dunno about the flags. Every time I try that, it does bad things. For example this works fine:
Redirect 301 /A/1028/B_C_D.php http://www.example.com/A/1028/E-F-G.php?
This throws an error:
Redirect /A/1028/B_C_D.php http://www.example.com/A/1028/E-F-G.php? [R=301,L]
