test-log: Add test for "hg log -pf" (issue647)

To test f786fc4b8764 we analyze this repo:

0 | 1 |   2    | 3  |   4
a  ------------> b
 \
    b -> dir/b -------> e

                 d

We follow dir/b and expects rev 0, 1 and 2.

A log following b will surprisingly report rev 0 and 1. That's because the
content and the parents are the same in rev 1 and rev 3, and the revlog entry
from rev 1 is thus reused in rev 3 even though the revlink is incorrect.

Note that if we follow e then we will get all revs, including rev 3, because b
gets added to the set of interesting filenames we are following through all
revisions. That might be surprising, but that's (currently) how it is.
