Subject: support pager.* for external commands
X-Git-Tag: v1.7.7-rc1~37^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=92058e4d3e032714da6d2df5fa1fe2cf612979a5;p=git.git

support pager.* for external commands

Without this patch, any commands that are not builtin would
not respect pager.* config. For example:

  git config pager.stash false
  git stash list

would still use a pager. With this patch, pager.stash now
has an effect. If it is not specified, we will still fall
back to pager.log when we invoke "log" from "stash list".
