[Ingo Schwarze]

schwarze pushed a commit to branch master
in repository groff.

commit f1af4b0b05e79c96cef886442681e12b3fca0184

    Makefile.am: correctly calculate MAJOR_VERSION etc.
    
    In a BRE, "\+" does not mean "one or more repetitions".
    Fix the calculation by using cut(1) instead of sed(1),
    which is also in POSIX and much simpler for this task.
    OK wl@
