Yes we have a similar code lying out in the function
'get_wc_target_merge_info' inside subversion/libsvn_client/diff.c. If
you make get_src_merge_info public(that is what I meant when I said
export(static functions are not exported) it ) we can reuse it there and
possible future consumers like subcommands like 'svn mergeaudit'.
May be we can call it svn_client_get_mergeinfo_for_single_path() ??

No need to ensure that. Across our code, atleast the places where I have
seen, the callee always sets the apr_hash_t*. Checking for NULL there is
In this particular case refer 'svn_repos_fs_get_merge_info' in
subversion/libsvn_repos/fs-wrap.c you will realize that 'src_mergeinfo'
will never be NULL.
Anyway I could see this kind of too cautious(????) null checking atleast
in 2 instances(for which my patch found its place in issue tracker!!!,
and hence did not give much motivation to dig further.)

Oh I misunderstood!.
I thought 'get_implied_merge_info' would get the 'svn:mergeinfo' as
available on 'copy_from_source_path'. I am wrong it just gives the
'copy_from_source_path:created_rev-cur_rev'. So we need both this
mergeinfo and mergeinfo crawl on 'copy_from_mergeinfo'.
