Fix lintian warning acute-accent-in-manual-page In case this tag was emitted for the second half of a '\\' sequence, this is indeed no acute accent, but still wrong: A literal backslash should be written \e in the groff format, i.e. a '\\' sequence needs to be changed to '\e' which also won't trigger this tag. . Please refer to Bug#554897, Bug#507673, and Bug#966803 for details.
