need a specification of "-b -" in the man page

Description

When our group did fuzzing about curl, we found a seed input which makes curl hang on there.
After we analyzed the problem, we found we have one string "-b-" inside the config file and curl asked input content. So it hangs on.

Thanks, the man page is now updated! (the web version will reflect this soon too, but it can take up to 24 hours until it does)
