Originally, we would use "VAR=VAL command" to execute a test command with
environment variable(s) only for that command. This does not work for commands
that are shell functions (most notably test functions like "test_must_fail");
the result of the assignment is retained and affects later commands.
To avoid this, we assigned and exported the environment variables and run
the test(s) in a subshell like this,
(
VAR=VAL &&
export VAR
test_must_fail git command to be tested
)
Using the "env" utility, we should be able to say
test_must_fail git command to be tested
which is much short and easier to read.

Git prompts me for this but I don't know what to type. I tried typing just
the id, like 244379 and that didn't work. I guess I'll try
244379@gmane.comp.version-control.git? Google didn't bring many results on
how to use it but many results of what it is and its goal.

I'll ignore this for now. If needed I can make another patch to resolve this.
Hopefully this should be all of it.
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][2]. 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.
