[HarfBuzz] a bug in configure in Pango harfbuzz-ng-external branch

[suzuki toshiya]

Hi Behdad,

I'm not sure if this should be posted to gtk+-i18n list or here.
If harfbuzz list is inappropriate list to discuss, please let
me know.

The configure.in of Pango harfbuzz-ng-external branch has a line
like:

*)         IFS="$pango_save_ifs" AC_MSG_ERROR([specified module $module not recognized]) ;;

I'm afraid that multiple command separated by space in single
line is danger in shell script (in my case, configure script
gets the error here during the running). So, I prefer this line
should be divided to 2 lines aslike:

diff --git a/configure.in b/configure.in
index 87fe0e9..b3a7e0b 100644

Is this wrong fix?

P.S.
There is no way to file a bug specific to harfbuzz-ng-external branch
in current bugzilla in gnome.org. I'm sorry for posting a silly patch
