In most cases, this ensures users will only have to opt-in to
using -extindex once and won't have to issue extra commands
to keep external indices up-to-date when using
public-inbox-index.

Since we support arbitrary numbers of external indices for
ease-of-development, we'll support repeating "-E"
("--update-extindex=") in case users want to test changes in
parallel.

+=item --update-extindex=EXTINDEX, -E
+
+Update the given external index (L<public-inbox-extindex-format(5)>.
+Either the configured section name (e.g. C<all>) or a directory name
+may be specified.
+
+Defaults to C<all> if C<[extindex "all"]> is configured,
+otherwise no external indices are updated.
+
+May be specified multiple times in rare cases multiple external
+indices are configured.
+
+=item --no-update-extindex
+
+Do not update the C<all> external index by default.  This negates
+all uses of C<-E> / C<--update-extindex=> on the command-line.
