However, the "email" pointer may be NULL here if we were planning to fill it in later from ident_default_email(). This was broken by `59f929596` (fmt_ident: refactor strictness checks, 2016-02-04). Prior to that commit, we would look up the default name and email before doing any other actions. So one solution would be to go back to that. However, we can't just do so blindly. The logic for handling the "!email" condition has grown since then. In particular, looking up the default email can die if getpwuid() fails, but there are other errors that should take precedence. Commit `734c7789a` (ident: check for useConfigOnly before auto-detection of name/email, 2016-03-30) reordered the checks so that we prefer the error message for useConfigOnly. Instead, we can observe that while the name-handling depends on "email" being set, the reverse is not true. So we can simply set up the email variable first. This does mean that if both are bogus, we'll complain about the email before the name. But between the two, there is no reason to prefer one over the other.

ident: handle NULL email when complaining of empty name

If we see an empty name, we complain about and mention the
matching email in the error message (to give it some
context). However, the "email" pointer may be NULL here if
we were planning to fill it in later from ident_default_email().

This was broken by 59f929596 (fmt_ident: refactor strictness
checks, 2016-02-04). Prior to that commit, we would look up
the default name and email before doing any other actions.
So one solution would be to go back to that.

However, we can't just do so blindly. The logic for handling
the "!email" condition has grown since then. In particular,
looking up the default email can die if getpwuid() fails,
but there are other errors that should take precedence.
Commit 734c7789a (ident: check for useConfigOnly before
auto-detection of name/email, 2016-03-30) reordered the
checks so that we prefer the error message for
useConfigOnly.

Instead, we can observe that while the name-handling depends
on "email" being set, the reverse is not true. So we can
simply set up the email variable first.

This does mean that if both are bogus, we'll complain about
the email before the name. But between the two, there is no
reason to prefer one over the other.
