Title: Respect absolute paths in compute_source_path.

When using compute_source_path to determine the full path of an
asset, if our source begins with '/', we don't want to include
the directory. Examples are illustrative:

> compute_source_path("foo", "stylesheets", "css")
> compute_source_path("/foo", "stylesheets", "css")

Before this patch, the second example would return the same as the
first.

Fixes #5680.

If this is accepted, I will also backport to 3.2.
