I am using "includeIf.gitdir:/work". I tried to reproduce it at my home 
workstation where I have the exact same configuration, but in the 
beginning I couldn't. Then I realized, that at work the /work folder is 
actually a symlink to a different directory. When I did the same at 
home, I could reproduce the issue:

% pwd
/work/repo
% git send-email --dry-run -1 --to nobody | grep ^From
From: Konstantinos Dalamagkidis <work-email@example.com>
% cd ../repo-symlink
% git send-email --dry-run -1 --to nobody | grep ^From
From: Konstantinos Dalamagkidis <personal-email@example.com>
% realpath .
/home/dalamagkidis/tmp/repo

It appears that git-config and git-send-email parse the gitdir slightly 
differently when it comes to symlinks. More specifically git-send-email 
uses the realpath of the repository to determine which configuration to 
use. It also explains why nobody came across this problem before.
