About an svn_opt_args_to_target_array3 that returns two array's, one full of
inputs that matched admin directory names, and one full of inputs that
didn't. That way if the caller wants to warn about admin dirs he's
skipping, he can do:
for (i = 0; i < admin_targets->nelts; i++)
target = APR_ARRAY_IDX(admin_targets, i, const char *);
for (i = 0; i < real_targets->nelts; i++)
target = APR_ARRAY_IDX(real_targets, i, const char *);
If the caller *doesn't* want to warn, he doesn't have to.
In fact, maybe the API could be such that if you passed NULL for the
admin_targets parameter, the o-a-t-t-a3 wouldn't do the splitting/filtering,
for callers that don't want to treat admin directories specially.
I dunno ... just some ideas.
