Re: [PATCH 2/2] Use 'env' to find perl instead of fixed path

You may still want the 1/2 patch in this series, just to make things
internally consistent with "-w" vs "use warnings;" inside git's perl
scripts.

I do not think so.  1/2 is justified as a prerequisite of 2/2 and
needs a different log message, so cannot be used as is.

I vaguely recall hearing arguments for and against the choice
between "#!path-to-perl -w" vs "use warnings;" but do not recall the
details to have a strong opinion either way, so we might even end up
wanting to be "internally consistent" by going the other way.  Please
prepare a standalone patch with an update message to convince people
why "use warnings;" is more preferable than "#!path-to-perl -w" and
explaining that we are making things consistently use the more
preferable form, if you want to go in that direction.

Thanks.
