PROBLEM:  (QAR 58706)    (Patch ID: OSF435-425316)

This patch fixes a problem with the vi editor environment variable EXITIT that
occurs when EXINIT includes the editor's so subcommand.

When EXINIT included an so subcommand for a file which itself contained an
so subcommand to a second file, the editor would exit without an error message
whenever the second file did not exist.
