[PATCH v4 0/6] Pull out require_clean_work_tree() functionality from builtin/pull.c

[Johannes Schindelin <johannes.schindelin@gmx.de>]

This is the 5th last patch series of my work to accelerate interactive
rebases in particular on Windows.

Basically, all it does is to make reusable some functions that were
ported over from git-pull.sh but made private to builtin/pull.c.

Changes since v3:

- reworded 3/5's commit message according to Junio's suggestion.

- fixed a tyop in 4/5's commit message, pointed out by Jakub.

- marked the hint "please commit or stash them" (reintroduced from the
  original git-pull.sh script) as translatable.

- changed the exit code to 128 (emulating a die()) if
  require_clean_work-tree() was asked to be non-gentle.

- fixed a tyop in 3/6 (which was replaced in 4/6, but it is good not to
  introduce bugs only to fix them right away).

- prefixed the commit message of 4/6 with the "wt-status:" prefix,
  replicating Junio's commit message in the `pu` branch.


Johannes Schindelin (6):
  pull: drop confusing prefix parameter of die_on_unclean_work_tree()
  pull: make code more similar to the shell script again
  wt-status: make the require_clean_work_tree() function reusable
  wt-status: export also the has_un{staged,committed}_changes()
    functions
  wt-status: teach has_{unstaged,uncommitted}_changes() about submodules
  wt-status: begin error messages with lower-case
