Subject: (tail_forever): Do not treat
X-Git-Tag: SH-UTILS-2_0_12~17
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=15bef4ddb6d0223fd80b52c84e888a50a2910bd8;p=thirdparty%2Fcoreutils.git

(tail_forever): Do not treat
max_n_unchanged_stats_between_opens specially (as if it were
infinite) if it has its maximal value.  Similarly for
max_n_consecutive_size_changes_between_opens.
