[PATCH v3 0/5] rebase/progress: add and use term_clear_line()

This series fixes some garbled progress display in 'git rebase' and simplifies clearing up the progress display in general.

Only slight updates since the previous version to remove one of the "Yuck"s by making the offending test in t3404 more focused, making the first patch of the previous version pointless. There is also a a preparatory cleanup patch 't3404: modernize here doc style'.

v2: https://public-inbox.org/git/20190611130320.18499-1-szeder.dev@gmail.com/T/#u

SZEDER Gábor (5):
  t3404: modernize here doc style
  t3404: make the 'rebase.missingCommitsCheck=ignore' test more focused
  pager: add a helper function to clear the last line in the terminal
  rebase: fix garbled progress display with '-x'
  progress: use term_clear_line()
