All aliases in ~/.bashrc are listed in emacs shells.
I already had have ansi-color-for-comint-mode-on set.
execution of ls traces to /bin/ls

Maybe i was not clear in the beginning, the emacs shell can show colors,
but not to my customization, for example, I customized it to show
executables in purple, it still show them in red. While a regular terminal
shows the desirable purple color for executables (as in below, left is
regular terminal, right is emacs shell).
