Not a good idea in general.

Sorry I didn't catch this earlier then.

I often have an "experimental" Perl earlier in my path than the
"official" Perl.  This would mean that I'd get different behaviors
running git from the command line than I would from automated tools, and
it would be relatively confusing.

The official Perl should be in /usr/bin or /usr/local/bin, and that's
the one you should use with Git.  *Or*, give the installer a knob to
configure.

But please don't use env.  Heck, some systems might not even *have*
env.  And some systems have it in /bin and not /usr/bin.  Don't ruin
portablity at this point, please.
