A bug was introduced in b97bbf8 with the fix for Eshell, where the abbreviated path was not used anymore. This commit fixes it. This commit also introduces the new macro `phundrak/var-or-if-nil' which is documented in the code. It has replaced some code already. The coding style of some recent functions have been updated too, arguments names now begin with a dollar `$' sign. This is just stylistic and it has no influence on the code whatsoever. Finally, some nested `if's in `phundrak/abbr-pwd' were converted in a single `cond', which led to renaming two variables in order to avoid a collision between the variable and the function `push' – `pull' has been renamed accordingly.
