Re: [PATCH] t0300-credentials: Word around a solaris /bin/sh bug

> Solaris' /bin/sh was making the IFS setting permanent instead of
> temporary when using it to slurp in credentials in the generated
> 'dump' script of the 'setup helper scripts' test in t0300-credentials.
>
> The stderr file that was being compared to expected-stderr contained the
> following stray line from the credential helper run:
>
> warning: invalid credential line: username foo
>
> To avoid this bug, capture the original IFS and force it to be reset
> after its use is no longer required.  For now, this is lighter weight
> than altering which shell these scripts use as their shebang.
