Currently textconv helpers are run directly. Running through the shell is useful because the user can provide a program with command line arguments, like "antiword -f". It also makes textconv more consistent with other parts of git, most of which run their helpers using the shell. The downside is that textconv helpers with shell metacharacters (like space) in the filename will be broken. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
