--exclude broken under 1.13

[Robert Minsk]

The behavor of exclude has changed from 1.12 to 1.13 and no longer seems to
work.

>From the docs:

   Periods (`.') or forward slashes (`/') are not considered special
for wildcard matches.  However, if a pattern completely matches a
directory prefix of a matched string, then it matches the full matched
string: excluding a directory also excludes all the files beneath it.

>From the ChangeLog:

* src/list.c (read_and):
        Use excluded_filename instead of check_exclude.
        Check base name of incoming file name, not entire file name, when
        deciding whether to exclude it.

This is what seems to be broken

I have reverted back to tar-1.12 for the time being.

Some examples:

> gtar --create --exclude=tools/sgi -f /dev/null -v .  
./
tools/
tools/sgi/
tools/sgi/sys/
tools/sgi/sys/packages/
tools/sgi/sys/packages/BAR

> gtar --create --exclude=./tools/sgi -f /dev/null -v .
./
tools/
tools/sgi/
tools/sgi/sys/
tools/sgi/sys/packages/
tools/sgi/sys/packages/BAR

> gtar --create --exclude=tools/sgi/. -f /dev/null -v .  
./
tools/
tools/sgi/
tools/sgi/sys/
tools/sgi/sys/packages/
tools/sgi/sys/packages/BAR

> gtar --create --exclude=./tools/sgi/. -f /dev/null -v .
./
tools/
tools/sgi/
tools/sgi/sys/
tools/sgi/sys/packages/
tools/sgi/sys/packages/BAR

> gtar --create --exclude=tools/sgi/* -f /dev/null -v .  
./

tools/sgi/
tools/sgi/sys/
tools/sgi/sys/packages/
tools/sgi/sys/packages/BAR

> gtar --create --exclude=./tools/sgi/* -f /dev/null -v .
./
