Comment 32 for bug 64064

I have tested my patch.

It works well with:
 * bash
 * dash
 * ksh
 * ash

But does not work with:
 * zsh
 * csh
 * fish
 * tcsh
 * es
 * rc
 * sash

I did not see any ill-effects on the shells where it didn't work, besides not finding executables in ~/bin. And I think we have the vast majority of Ubuntu's shell users covered with (bash, dash, ksh, ash).
