write-editor-version in Editors
(write-editor-version -> boolean
out out-base)
out : editor-stream-out% object
out-base : editor-stream-out-base% object
Writes version information to out-base in preparation for
writing editor information to the stream out.
The out argument is currently not used, but out-base
should be the base for out. In the future, out may record
information about the version for later version-sensitive output.
The result is #t if the write succeeded, #f otherwise.
