The in-kernel process name is limited to 16 bytes (including null terminator), and this is unlikely to be changed. Therefore I will reassign this back to bash-completion. You need to look at how killall matches commands and replicate that. It is probably reading the full command line (/proc/*/cmdline) and taking the basename of the first string.
