6     ** 	Common procedure to output a line of text depending on user-provided
7     ** 	options of how to print.
8     **
9     ** Parameters:
10    **	@print_lnumbers		- Boolean whether to print line#s.
11    **	@right_just		- Boolean; to right-justify line#s.
12    **	@print_lcomment		- Print line#s in comment /* */
13    **	@grep_ctxt		- Boolean whether we are in a context search
14    **	@linenum		- Line # of current line being output
15    **	@subtext		- Piece of SQL sub-text extracted, to print.
16    **	@tagline		- Code returned from sp_showtext_check_print
17    **				  (2=>line is the tag line in context block.)
18    **	@trace			- Trace flag user passed-in.
19    **	@trace_hang_for_debug	- Trace flag under which to hang here to debug.
