From: Cord Seele <cowose@xxxxxxxxx>
cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30) broke
the expansion of aliases.
This was caused by treating %config_path_settings, newly introduced in
said patch, like %config_bool_settings instead of like %config_settings.
Copy from %config_settings, making it more readable.
Nb. there were a few issues that were responsible for this error:
1. %config_bool_settings and %config_settings despite similar name have
different semantic.
%config_bool_settings values are arrays where the first element is
(reference to) the variable to set, and second element is default
value... which admittedly is a bit cryptic. More readable if more
verbose option would be to use hash reference, e.g.:
my %config_bool_settings = (
"thread" => { variable => \$thread, default => 1},
[...]
Or something like that.
%config_settings values are either either reference to scalar variable
or reference to array. In second case it means that option (or config
option) is multi-valued. BTW. this is similar to what Getopt::Long does.
2. In cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30)
the setting "aliasesfile" was moved from %config_settings to newly
introduced %config_path_settings. But the loop that parses settings
from %config_path_settings was copy'n'pasted *wrongly* from
%config_bool_settings instead of from %config_settings.
It looks like cec5dae author cargo-culted this change...
3. 994d6c6 (send-email: address expansion for common mailers, 2006-05-14)
didn't add test for alias expansion to t9001-send-email.sh

Something like this?
Nb. I was not sure whether to keep Cord authorship...
