Bug 30673

emacs24-common-24.3-alt8

I have installed "topgit" from nixpkgs (as described at http://nixos.org/nix/ :  curl https://nixos.org/nix/install | sh ; make sure that ~/.nix-profile/bin is in your PATH -- .bash_profile gets updated by the installation procedure;  nix-env -i topgit).

In eshell, it doesn't work:

$ ~/.nix-profile/bin/tg create example-simple_/essence
/nix/store/cxrc12hkmvrjlq747cm08av6jl41nzi1-bash-4.3-p30/bin/sh:  : No such file or directory
$ 

In a normal terminal with shell, it works.

Also, the following works successfully in eshell, too:

$ strace -e trace=file -fF ~/.nix-profile/bin/tg create example-simple_/essence

It seems that I catched a similar bug in eshell a long time ago: once I couldn't successfully finish an "rpm -ba ..." build process in eshell (or "gear-hsh").

I had a guess that it's caused by broken signal handling or child process management in eshell...
