Hi,

I worked this over a bit (I hope Dmitry won't mind) and I am now more or
less happy with the patch. Here is list of changes I made:
- rebased to todays master (Oid conflicts, transforms patch conflicts)
- changed the main if/else if/else if/else to switch in replacePath
- split the replacePath into 3 functions (main one plus 2 helpers for
Object and Array)
- removed the h_atoi and use the strtol directly
- renamed jsonb_indent to jsonb_pretty because we use "pretty" for
similar use-case everywhere else
- fixed whitespace/brackets where needed
- added/reworded some comments and couple of lines in docs

I think it's ready for Andrew now.
