Johannes Sixt bfa7d01413 t4018: an infrastructure to test hunk headers
Add an infrastructure that simplifies adding new tests of the hunk
header regular expressions.

To add new tests, a file with the syntax to test can be dropped in the
directory t4018. The README file explains how a test file must contain;
the README itself tests the default behavior.

How to write RIGHT test cases
=============================
Insert the word "ChangeMe" (exactly this form) at a distance of
at least two lines from the line that must appear in the hunk header.
The text that must appear in the hunk header must contain the word
"right", but in all upper-case, like in the title above.
To mark a test case that highlights a malfunction, insert the word
BROKEN in all lower-case somewhere in the file.
This text is a bit twisted and out of order, but it is itself a
test case for the default hunk header pattern. Know what you are doing
if you change it.
BTW, this tests that the head line goes to the hunk header, not the line
of equal signs.
