My recent change in this area wasn't quite right.
For example, before,
: > k; ./tail -f - k < .
would revert to sleep-based implementation.
With this patch, since "-" ends up being ignored, the inotify-based
implementation is used.

Subject: [PATCH] tail: don't give up on inotify mode for an already-ignored "-"
* src/tail.c (main): Adjust today's change to honor the
F[i].ignore flag that may have been set in tail_file.
