[PATCH] configmake: correct minor inconsistency in Makefile rule

[Jim Meyering]

I noticed a small inconsistency: even with V=0, make would still
echo this command:

    mv -f lib/configmake.h-t lib/configmake.h

Every other modules/* snippet did it differently:

    $ g grep -B1 mv.-f modules/*
    modules/alloca-opt-     } > $@-t && \
    modules/alloca-opt:     mv -f $@-t $@
    --
    modules/argz-   } > $@-t && \
    modules/argz:   mv -f $@-t $@
    --
    modules/byteswap-       } > $@-t && \
    modules/byteswap:       mv -f $@-t $@
    --
    modules/fnmatch-        } > $@-t && \
    modules/fnmatch:        mv -f $@-t $@
    --
    modules/getopt-posix-   } > $@-t && \
    modules/getopt-posix:   mv -f $@-t $@
    --
    modules/glob-   } > $@-t && \
    modules/glob:   mv -f $@-t $@
    --
    modules/poll-h- } > $@-t && \
    modules/poll-h: mv -f $@-t $@
    --
    modules/sys_resource-   } > $@-t && \
    modules/sys_resource:   mv -f $@-t $@
    --
    modules/sys_socket-     } > $@-t && \
    modules/sys_socket:     mv -f $@-t $@
    --
    modules/sys_uio-        } > $@-t && \
    modules/sys_uio:        mv -f $@-t $@
    --
    modules/sysexits-       } > $@-t && \
    modules/sysexits:       mv -f $@-t $@

This makes configmake's rule consistent:

Subject: [PATCH] configmake: correct minor inconsistency in Makefile rule

* modules/configmake (Makefile.am): All other rules like this one
run the final "mv -f ..." in the same backslash-continued command
as the one that does everything else.  This one put the mv -f ...
command on a separate, non-backslash-continued line.
Make it like the others.
