Some problems with Terminal and Zipper

[A. Arias]

These problems are with stable releases of the apps and GNUstep from
SVN.

If you type the character "_" many times in Terminal, it show something
like "_ _ _ _ _ _ _". Now if you try to delete this with backspace,
terminal don't allows delete all the characters.

In Zipper each time you open a tarball, Zipper select the last file. So,
if you extract the package only the last file is extracted. You need
select all files to extract the package (or unselect the last file, if
this is possible).
