VI question: how to initialize a named buffer from EXINIT?

[Ken Turkowski]

I'd like to initialize a named buffer (maybe more) with some well-used
commands (like removing blanks at the end of a line), so that I only
need to execute the @<bufname> command to execute them.  I know that I
can load them up with a yank or delete, but is it possible to do it
from EX mode, suitable for initializing from the EXINIT environment
variable or the ~/.exrc file?
