* font/devps/prologue.ps (EP): Dont' use `bind'. Reason: Using
`bind' to define a procedure which contains `showpage' means that an
invocation of `showpage' may execute wrongly (the exact effect
depending on the interpreter). Not usually a problem except under
transformations, such as combining pages.
(PEND): Don't call `clear'. Reason: Using `clear' in the definition
of /PEND means that stack underflow will occur if the stack is
deliberately non-empty before document inclusion. If included
files are found to be generally badly behaved, we could replace the
`clear' with `mark' in /PBEGIN and `cleartomark' in /PEND (I've
never found this necessary).
