Bugzilla Bug 169617

app-emacs/cedet-1.0_pre3-r2 breaks the tree structure of its elisp directories
in src_install().

For example, the "bovine", "wisent", and "test" sub-directories are installed
under /usr/share/emacs/site-lisp/cedet while they should really go into
/usr/share/emacs/site-lisp/cedet/semantic where cedet expects them.

In fact, src_install() does weird things:

    find "${S}" -type f -print \
        | while read target; do
            local directory=`dirname $target` file=`basename $target`
            local sub_directory=`basename $directory`

followed by a long case instruction installing files in ${sub_directory}
(relative to different locations, depending on suffixes). The last statement
will just "flatten" the directory tree, putting all directories directly into
the tree's root node.

Proposed bugfix:
Replace the last line listed above by:
            local sub_directory=`echo $directory | sed "s%^${S}/*%%;s/^$/./"`
which will preserve the directory tree structure.

To illustrate it further, directory structure under /usr/share/emacs/site-lisp
should be (and is in ${S}):

cedet-+-cogre
      |-common---icons
      |-contrib
      |-ede
      |-eieio
      |-semantic-+-bovine
      |          |-tests
      |          |-wisent
      `-speedbar

But the ebuild installs the following (note the first line!):

cedet-+-cedet-1.0pre3
      |-bovine
      |-cogre
      |-common
      |-contrib
      |-ede
      |-eieio
      |-icons
      |-semantic
      |-speedbar
      |-tests
      `-wisent

Fixed, thanks.
