suggest PREFIX option [rt.cpan.org #49726]

It'd be good if File::Temp had a PREFIX option like

    $fh = File::Temp->new (PREFIX => 'myprog');

which would generate a file "/tmp/myprogXXXXXX".

Emacs make-temp-file has this and it's a good way to work a program name
or module name into the filename, as a hint at who's to blame for
filling up /tmp. :-)

I got the effect I wanted with a TEMPLATE, but that then needs TMPDIR
turned on explicitly, and in any case I'd rather let File::Temp decide
how many "XXXXXX"s are prudent etc.

    $fh = File::Temp->new (TEMPLATE => 'myprog-XXXXXX',
                           TMPDIR => 1);

Should PREFIX be ignored if DIR specified?

Vote for this feature. Prefix for directories would be nice to have too.
