 What about the following sed version:

        @$(ECHO) "Line numbers with incorrect continuation in Makefile.am:"
        sed -n '/\\$$/{ N; /\\\n[^ \t]/=; D; }' Makefile.am

? It took me some time to realize that I had to use "D" to avoid skipping
every second line but the version above seems to work fine. It doesn't
return a non-null exit code if it matches but considering that there could
be more tests to perform after it anyhow this is probably not a big
problem.

 Thanks,
