Gimp batch-mode patch

Background

Gimp provides a remotely-scriptable interface when invoked with the "-b -" option. Unfortunately, the the scheme interpreter wrapper used for command-line interaction uses stdio for read/write, but does not flush writes to stdout. Responses to commands are never flushed to the return pipe, causing scripts to hang waiting for a response.

Fix

A single fflush(stdout); addition to scheme-wrapper.c in the script-fu plugin fixes the problem. Note that even when gimp is configured with --enable-static and --disable-shared, the fix is in the script-fu plugin, not in the GIMP application itself. make install is likely necessary to ensure the fixed plugin is loaded by any local build.
