[PATCH v5 0/7] "git reset --merge" related improvements

Another reroll with the following changes:

- the name of the new option is now "--keep" instead of "--keep-local-changes",
- the fill_tree_descriptor() function is used instead of adding a new
parse_and_init_tree_desc() function (thanks to Stephen Boyd),
- patch 1/7 was added to only accept soft reset when not in a working tree;
this makes the test suite pass,
- the commit message of patch 4/7 that adds the --keep option has been
improved; it talks more about the use case of this new option.

Christian Couder (6):
  reset: do not accept a mixed reset in a .git dir
  reset: add a few tests for "git reset --merge"
  reset: add option "--keep" to "git reset"
  reset: add test cases for "--keep" option
  Documentation: reset: describe new "--keep" option
  Documentation: reset: add some tables to describe the different
    options

Stephan Beyer (1):
  reset: use "unpack_trees()" directly instead of "git read-tree"
