This introduces a special case just for handling $smtp_server…

Yes, and that was very much deliberate, as I think

	git send-email --smtp-server=~/bin/my-phoney-sendmail

won't be affected by %config_path_settings.  $smtp_ssl_cert_path has
the same problem already, and I didn't want to make things worse (I
think %config_path_settings is a mistake---it is fine to have a list
of variables that can use ~tilde expansion, but I do not see why it
makes sense to allow the ~tilde expansion when the value came from
configureation files, and not from the command line).

Well, unless I'm missing something, shouldn't the tilde above be
expanded by the shell before actually being passed as argument?

$ echo simulate --smtp-server=~/bin/my-phoney-sendmail
simulate --smtp-server=/home/khardix/bin/my-phoney-sendmail

I assumed that only the config values are handled specially
because only they need that – the CLI is handled by shell in advance.
Never played with $smtp_ssl_cert_path though,
so if there are known problems, just ignore me
– or better, point me to the relevant issue/discussion,
if you can be bothered :) Thanks.

My concern was that if there is a SMTP server actually named
i.e. `~someone.example.org`, this change would break that.

Can tilde appear in a valid DNS name?  I doubt it.

So I actually did my homework and skimmed through the relevant RFCs
(RFC952 and RFC1123); as it turns out, no, it cannot
– only ASCII alphanumerics, '-' and '.' are valid characters.
