OMG! It teleported all my code to Narnia! How it's possible? LOL
Of course nothing wen't wrong. Tested both ways, did what they had to do. Seems all fine, since after all is only indenting normal code. Nice work. However I feel that indent blocks should be the default one (nobody normally comments other things in blocks than code right?).

this switch is a bit hard to remember and long to type --indentblockcomment?? you really don't want people other than standard options! ;D
(I will start from now do a .bat with personal settings)

Small notice: couldn't be a bit intrusive that prettifier replaces old *.ind without permission? (for me it's fine since don't have to delete old *.ind when testing but other people perhaps could not like it).
