Subject: rebase -i: fix interrupted squashing
X-Git-Tag: v1.5.3-rc4~55
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=fb47cfbd59b12ea67e1a5c6a9d0bd665fcae4581;p=git.git

rebase -i: fix interrupted squashing

When a squashing merge failed, the first commit would not be replaced,
due to "git reset --soft" being called with an unmerged index.

Noticed by Uwe Kleine-König.
