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

From: SZEDER Gábor <[email-masked]>
Date: Mon, 24 Jun 2019 20:13:13 +0200

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/[email-masked]/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()
