We can see that this date string lacks timezone information, which
would likely fall back to whatever timezone the user is in. Is that
what we want? I am guessing it is, as we are dealing with "now"
timestamp, but wanted to double check.

Or make sure ignore_author_date() does not leak the original, when
it rewrites its parameter.
But I have a larger question at the higher design level. Why are we
passing a single string "author" around, instead of parsed and split
fields, like <name, email, timestamp, tz> tuple? That would allow us
to replace only the time part a lot more easily. Would it make the
other parts of the code more cumbersome (I didn't check---and if
that is the case, then that is a valid reason why we want to stick
to the current "a single string 'author' keeps the necessary info
for the 4-tuple" design).

Or require callers to pass a free()able memory to ignore_author_date()
and have the callee free the original?
