bin/arch --start and --end argument handling

[Fehwalker-users]

bin/arch says (among other things):

    -s N

    --start=N

        Start indexing at article N, where article 0 is the first in the
mbox.
        Defaults to 0.

    -e M

    --end=M

        End indexing at article M. This script is not very efficient with

        respect to memory management, and for large archives, it may not be

        possible to index the mbox entirely. For that reason, you can
specify
        the start and end article numbers.

However, using --end=[some #] or --start=[some #] results in these errors:

% bin/arch --wipe --end=25000 test
[...]
option --end must not have an argument
% bin/arch --wipe --start=25001 test
[...]
option --start must not have an argument

Using --end [some #] or --start [some #] (ie with no =) works fine.

So either the help output of bin/arch needs to be amended to remove the
='s, or the argument handling needs to be tweaked to understand ='s. I'm
unsure which is preferable.
