The "shortlog" command defaults to HEAD only when its standard input is
connected to a terminal; otherwise it acts in the traditional "filter"
mode to read and summarize the "git log" output.
Two new tests added to t4203 assumed that the command always default to
HEAD, but when the standard input is closed (or connected to /dev/null),
it output empty, which is a summary of its empty input, causing the test
to break.

A seemingly innocuous change like adding test_tick somewhere can
completely upset the final mailmap test, since it checks commit
hashes and dates. Make the test less fragile by fuzzing away the
unpredictable parts and leaving in the authors (which is what the
test is about, anyway).

On an x86_64 system (F13-based), I ran these commands in an empty directory:
git init
printf '%s\n' \
'<jdoe@example.com> <jdoe@example.COM>' \
'John <jdoe@example.com>' > .mailmap
git shortlog < /dev/null
Here's the result:
(reading log message from standard input)
*** glibc detected *** git: free(): invalid pointer: 0x0000000000f53730 ***
======= Backtrace: =========

zsh: abort (core dumped) git shortlog
What happened?
Some .mailmap entry is of the <email1> <email2> form,
while a subsequent one looks like "User Name <Email2>,
and the two email addresses on the right are not identical
but are "equal" when using a case-insensitive comparator.
Then, when add_mapping is processing the latter line, new_email is NULL
and we free me->email, yet do not replace it with a new strdup'd string.
Thus, when later we attempt to use the buffer behind that ->email pointer,
we reference freed memory.
The solution is to free ->email and ->name only if we're about to replace them.

This allows us to augment the repo mailmap file, and to use
mailmap files elsewhere than the repository root. Meaning
that the entries in mailmap.file will override the entries
in "./.mailmap", should they match.
