traces: write the "Reading a token" alone on its line

The Java skeleton displays

    Reading a token:
    Next token is token "number" (1)

while the other display

    Reading a token: Next token is token "number" (1)

When generating logs in the scanner, the first part is separated from
the second, and the end of the scanner logs have the second part
pasted in.  So let's propagate the Java way, but with the colon.

* data/skeletons/glr.c, data/skeletons/lalr1.cc, data/skeletons/lalr1.d,
* data/skeletons/lalr1.java, data/skeletons/yacc.c: Do it.
Adjust test cases and doc.
