Title: Overhaul of partest-ack.

Seems like many/most options to partest are broken. Working
around as much as I can to make this thing useful again, plus
lots of improvements in robustness. Spaces and such are
preserved properly now, and I added a new way of selecting
tests based on time.
```
tools/partest-ack -s 1.week.ago
% tests modified since time ... 66

tools/partest-ack 'case object (Foo|Bar)'
% tests with matching paths ... 0
% tests with matching code ... 7
```
File paths and file contents are uniformly acked now, so
for instance this works as expected.
```
tools/partest-ack -i VIRTPAT
% tests with matching paths ... 41
% tests with matching code ... 11
# 43 tests to run.
```
