make test does not generate linked png images

[Reinhold Kainhofer]

Hi all,
When running "make test", the png images linked from the collated-files.html 
file are not generated. The following patch for GNUmakefile.in seems to fix 
this, but I don't know if that's the correct solution to create the files:

                echo -e '\n\n\n' ; \
                git diff ; \
        fi > input/regression/out-test/tree.gittxt
-       $(MAKE) -C input/regression/ out=$(OUT_TEST) 
LILYPOND_BOOK_LILYPOND_FLAGS="-dbackend=eps --formats=ps 
$(LILYPOND_JOBS) -dseparate-log-files -dinclude-eps-fonts -dgs-load-lily-fonts 
--header=texidoc -I 
$(top-src-dir)/input/manual -ddump-profile -dcheck-internal-types 
-ddump-signatures -danti-alias-factor=1" 
LILYPOND_BOOK_VERBOSE= out-$(OUT_TEST)/collated-files.html
+       $(MAKE) -C input/regression/ out=$(OUT_TEST) 
LILYPOND_BOOK_LILYPOND_FLAGS="-dbackend=eps --formats=ps,png 
$(LILYPOND_JOBS) -dseparate-log-files -dinclude-eps-fonts -dgs-load-lily-fonts 
--header=texidoc -I 
$(top-src-dir)/input/manual -ddump-profile -dcheck-internal-types 
-ddump-signatures -danti-alias-factor=1" 
LILYPOND_BOOK_VERBOSE= out-$(OUT_TEST)/collated-files.html
        @find input ly -name '*.ly' -print |grep -v 'out.*/' | xargs 
grep '\\version' -L | grep -v "standard input" |sed 's/^/**** Missing 
version: /g' 
        rsync -L -a --exclude 'out-*' --exclude 'out' --exclude mf --exclude 
source --exclude mf $(outdir)/share input/regression/out-test/


Although hard to see in this diff, the only change is from "--formats=ps" 
to "--formats=ps,png". If this is the correct way, I'll merge together with 
my musicxml fixes.

Cheers,
Reinhold
