Actually, it appears to be a toggle:


# Format is /regexp/flags or /regexp/flags!/regexp/flags
# where regexp is a regular expression as found in regexp(5), and flags  
are
# i: toggle ignore case (REG_ICASE - default is to ignore case)


Since the default is "ignore", I assume the /i toggle would be  
"enforce".
