[PATCH v2 00/19] reset improvements

Changes since v1:

 - Spelling fixes.

 - Explained how "git reset -- $pathspec" in bare repo is broken.

 - Provided motivation for replacement of switch by if-else

 - Fixed argv/argc handling by removing use of argc.

 - Replaced "don't refresh index on --quiet" patch by one that just
   inlines update_index_refresh()

 - Incorporated fixes from Junio's repo

 - Provided some motivation for "replace switch by if-else" amd moved
   the patch later in the series.

Thanks for reviewing!
