Log Message:
p5-ack: update to 2.24.

2.24    Thu Jun 21 22:41:49 CDT 2018
====================================
No changes since 2.23_03.

2.23_03 Fri Jun 15 23:18:42 CDT 2018
====================================
[ENHANCEMENTS]
Added --ts for Typescript.

[FIXES]
ack would stop searching if there was a file called "0" in the current
directory where ack was invoked. (GH #667)

2.23_02 Sat Jan  6 23:53:03 CST 2018
====================================
[FIXES]
t/ack-n.t was not calling lists_match() correctly.

[ENHANCEMENTS]
Added an optimization to make ack only do a line-by-line search of a
file if there's a match somewhere in the file.  This gives ack a 20-30%
in timings of common cases.

2.23_01
====================================
Broken. Deleted.
