Compiler warning in glob

[Colin Watson]

  gcc -DHAVE_CONFIG_H -I. -I../..     -g -O2 -Wall -W -Wpointer-arith

  glob.c: In function ‘glob_in_dir’:
  glob.c:1244: warning: declaration of ‘save’ shadows a previous local
  glob.c:1041: warning: shadowed declaration is here

The declaration here looks spurious, so this patch removes it.

        * lib/glob.c (glob_in_dir): Remove duplicate declaration of "save".
