Subject: The t_do bits are not set by this module. The t_next entry is used
X-Git-Tag: release-5-5~6095
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=c93761cadceed66e82ecd5f38736031eb36b8bbe;p=ack.git

The t_do bits are not set by this module. The t_next entry is used
to see whether the scan for this phase is already done.
t_do is now set in add_inputs(files.c).
