Originally, the code used subshells instead of FOO=BAR command because the variable would otherwise leak into the surrounding context of the POSIX shell when 'command' is a shell function. The subshell was used to hold the context for the test. Using 'env' in the test function sets the temp variables without leaking, removing the need of a subshell. Signed-off-by: David Tran <unsignedzero@xxxxxxxxx> --- Let's see if I replied correctly with send-email. I am David Tran a graduating CS/Math senior from Sonoma State University, United States. I would like to work with git for GSoC'14, specifically the line options for git rebase --interactive [1]. I have used git for a few years and know how destructive but important rebase is to git. I have created a few shell scripts here and there to make life using bash/zsh easier. I would like to apply these skills and work with the best.
