Bitten by Makefile.am syntax error

[Bob Friesenhahn]

A number of times I have been bitten by missing backslashes at the end 
of lines.  Automake does not warn.  A typical example is:

if !HasX11
TESTS_X11_XFAIL_TESTS =
        tests/rwblob_XWD_bilevel.sh \
        tests/rwblob_XWD_gray.sh \
        tests/rwblob_XWD_pallette.sh \
        tests/rwblob_XWD_truecolor.sh \
        tests/rwfile_XWD_bilevel.sh \
        tests/rwfile_XWD_gray.sh \
        tests/rwfile_XWD_pallette.sh \
        tests/rwfile_XWD_truecolor.sh
endif

Is there a way that Automake can reasonably produce warnings in this 
case?

Another issue with backslashes that I have encountered is that 
Automake doesn't like them at the end of comment lines.  It will issue 
a diagnostic for

#  some text \
#  some more text \

It seems to me that the comment should override the line continuation 
request.
