Because SVN in both our patches for tab completion missed filecomplete.h
and filecomplete.c I generated a new patch using ( diff -urN ) since
these files do not exist on stable/8.
Since the above files do not exist, the previous patches from des@ &
myself will break world builds.
This is the full patch:
sh-tab-complete-stable8.diff
These are the individual patches:
head_lib_libedit_filecomplete.c
head_lib_libedit_filecomplete.h
Again, apply these with:
cd /usr/src && patch -p1 </path/to/patchfile
