bug in make install

Ciao,

upon installing GIT I was bitten by the following behaviour of GNU Bash 3.1 (from the Info node "Bourne Shell Builtins"):

| If a non-empty directory name from `CDPATH' is used, or if
| `-'  is the first  argument, and  the directory  change is
| successful,  the  absolute  pathname  of the  new  working
| directory is written to the standard output.

this is triggered by setting "CDPATH=.", that is including "." in the list, when "templates/Makefile" does:

| (cd blt && $(TAR) cf - .) \
| (cd '$(DESTDIR_SQ)$(template_dir_SQ)' && umask 022 &&
$(TAR) xf -)

the absolute file name goes into the pipe and the "tar xf -" fails with a "this does not look like a tar archive" error. The problem is fixed by:

| (cd ./blt && $(TAR) cf - .)
|     ^^

Do not bother me asking why I put "." in CDPATH.

By the way: the use of tar annoys me a little because the installed files are 0640, rather than 0644, and I have to fix it while building my custom Slackware package. :/
