Subject: filter-branch: use $(($i+1)) instead of $((i+1))
X-Git-Tag: v1.5.3-rc0~69^2~6
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c12764b8b7e004f84b1e685b76f2d662bee8e196;p=git.git

filter-branch: use $(($i+1)) instead of $((i+1))

The expression $((i+1)) is not portable at all: even some bash versions
do not grok it. So do not use it.

Noticed by Jonas Fonseca.
