I have the following test file

|set terminal cairolatex pdf standalone mono dashed
|set output 'test.tex'
|test
|set output

when I use gnuplot 4 ("gnuplot 4.6 patchlevel 6", i.e., the version
packaged in Debian testing) I get the expected results, when I use
gnuplot 5 ("gnuplot 5.0 patchlevel 0" that I downloaded and installed
today by a simple "./configure ; make ' make install") things are
different... a "test.tex" and a "test-inc.pdf" are produced as well
but when I try to process "test.tex" things are not OK

I can see the resulting file "test.pdf" that looks correct except for
a non trivial aspect, i.e., all the different line types are the same
(the same problem is of course present also in the "test-inc.pdf"
file, directly produced by gnuplot)

Summarizing, using "cairolatex pdf mono dashed" there are two
problems, both introduced by 5.0 and not present in 4.6

 1. in the PDF file, using the options "mono dashed" all the lines are
    of the same, undashed type

 2. in the TeX file there is a minor error, that doesn't  prevent the
    compilation of the source but it's still an error

I add that these misbehaviors are not an artifact of the "test" command
but has been observed first during _normal_ operations

Thank you,
                                                g

ps: I had almost forgot to check...  also the "pdfcairo mono dashed"
terminal is affected by the same regression, i.e., all the lines are
not dashed
