Grep 2.6.3 disobeys --include option

[Gerald Britton]

If I have these files in my directory:

foo
bar
fum.txt

and I issue this command from this directory:

grep --include=*txt 'foobar'

I do not get the results expected as described by the option:

       --include=GLOB
              Search only files whose base name matches GLOB  (using  wildcard
              matching as described under --exclude).

Example:

$ls -l
total 12
-rw-r--r-- 1 jerryb jerryb 7 2011-01-23 17:43 bar
-rw-r--r-- 1 jerryb jerryb 7 2011-01-23 17:43 foo
-rw-r--r-- 1 jerryb jerryb 7 2011-01-23 17:43 fum.txt

$ cat *
foobar
foobar
foobar

Grep without --include option:

$ grep 'foobar' *
bar:foobar
foo:foobar
fum.txt:foobar

Grep with --include option:

$ grep --include=*txt 'foobar' *
bar:foobar
foo:foobar

As you can see, --include was treated like --exclude, which,
incidentally, gives the same results:

$ grep --exclude=*txt 'foobar' *
bar:foobar
foo:foobar

Grep version:

$ grep --version
GNU grep 2.6.3
