Subject: rebase: clearer names for directory variables
X-Git-Tag: v1.7.6-rc0~136^2~33
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=69a636ad1ac73a596d8c99a4206a6475b15e8d8d;p=git.git

rebase: clearer names for directory variables

Instead of using the old variable name 'dotest' for
"$GIT_DIR"/rebase-merge and no variable for "$GIT_DIR"/rebase-apply,
introduce two variables 'merge_dir' and 'apply_dir' for these paths.
