empty path into an absolute ("/") path.
* lisp/url/url-expand.el (url-expand-file-name): Properly resolve

This directory contains source code for the parts of Emacs that are
written in Emacs Lisp. *.el files are Emacs Lisp source, and the
corresponding *.elc files are byte-compiled versions. Byte-compiled
files are architecture-independent.
The term subdirectory contains Lisp files that customize Emacs for
certain terminal types. When Emacs starts, it checks the TERM
environment variable to get the terminal type and loads
'term/${TERM}.el' if it exists.
The other subdirectories hold Lisp packages grouped by their general
purpose.
