        usr.bin/mandoc : tbl_data.c 

Log message:
If a table contained at least one complete line
and on its last line, the first T{ remained unclosed,
roff_parseln() never returned ROFF_TBL for that last line,
so {man,mdoc}_addspan() never got called for that last line,
so we ended up with a table
where no line associated with a node had TBL_SPAN_LAST set,
so tbl_term() never free()'d the cols in struct roffcol,
so tblcalc() crashed on the NULL == tbl->cols assertion
when starting the *next* table in the same file.

Fix this by returning ROFF_TBL as soon as we open a data cell,
not only when finishing it - as explained above, it may never
get properly closed but instead be interrupted by .TE.

Problem reported by bentley@ in latex2man.1.

I love it when bugs take half a day to debug but
the fix turns out to be flipping one single bit in the source code.
