[MAN] Clarify "trap '' signals" syntax in manual page
When the manpage states | <action> may be null, which cause the specified signals to be ignored. it is not immediately obvious what it means for an action to be null. Clarify by explicitly referring to an empty string, as opposed to a NULL pointer or the string "null".
