That script gives me a repository I can test against. thanks.
The start_rev_list function calls parseviewrevs and expands the
arguments into a list of appropriate revision ids. In this case --all
gets expanded to a list of 1000 sha1 ids. This is appended to any
other view arguments and passed to git log on the command line
yielding our error.
git log can accept a --all argument it seems so it looks like we can
just short-circuit the parseviewrevs function when --all is passed in
and return --all instead of expanding the list. The following seems to
work for me with this test repository.
John, if this works for you can you also check that editing and
creating new gitk views on your real repository continues to work ok.

    Avoid expanding --all when passing arguments to git log.
    There is no need to expand --all into a list of all revisions as
    git log can accept --all as an argument. This avoids any
    command-line
    length limitations caused by expanding --all into a list of all
    revision ids.
