Custom field "help" text removal


I want to remove the help text that is displayed under custom fields,
such as “Enter one value”. I have grep’ed for this field and apart from
the .po translation files, this phrase appears in
/opt/rt3/lib/RT/ Does anyone know if it’s safe
or advisable to edit this file to remove the text? If not, how can I
remove this text?

Thanks in advance,
