> 
> Change the Perl Git utilities to use #!/usr/bin/env perl as a shebang
> instead of #!/usr/bin/perl. This makes e.g. git-send-email work if
> your personal perl has Net::SMTP::SSL, but your system perl doesn't.
> 
> This only affects shebangs in the uninstalled source tree. On
> installation shebangs will still be munged to PERL_PATH, which is
> currently /usr/bin/perl by default.
> 
> With this change all the code in Git that uses a shebang now uses
> /usr/bin/env, except those things that use /bin/sh and /bin/bash. All
> the Python code already used it, and some of the Perl code.
