[raster] regression failure due to underquoting

[gdt]

In r9235 (and I believe due to a change within the last week), make check fails in raster with

Creating spatial db postgis_reg 
createlang: language "plpgsql" is already installed in database "postgis_reg"
Adding raster support

 Something went wrong during db initialization (raster comments).
 For details, check /tmp/pgis_reg_7747/regress_log

which contains

psql:/home/gdt/SOFTWARE/POSTGIS/postgis/regress/00-regress-install/share/contrib/postgis/raster_comments.sql:322: ERROR:  syntax error at or near "BOTH"
LINE 1: ...egprocedure ) IS 'args: rast1, rast2, returnband='BOTH', oth...
                                                             ^

This is due, I think, to the following in raster/rt_pg/rtpostgis.sql.in:

CREATE OR REPLACE FUNCTION st_intersection(
	rast1 raster,
	rast2 raster,
	returnband text DEFAULT 'BOTH',
	otheruserfunc regprocedure DEFAULT NULL
)
	RETURNS raster AS
	$$ SELECT st_intersection($1, 1, $2, 1, $3, $4) $$
	LANGUAGE 'sql' STABLE;

The problem seems to be that the single quotes around BOTH are not themselves quoted when used inside a dcoumentation string.

I observed the problem with

  PostGIS is now configured for i386-unknown-netbsdelf5.1.

but strk reports seeing it as well, so it's not a NetBSD-specific issue.

Yep, it's doc/xsl/raster_comments.sql.xsl not escaping quotes in parameter lists.

I'm giving this a try, as I've found a nice "escapesinglequotes" template in other files. I wonder if we could reuse some of these templates using includes...

[strk]

r9237 fixes this. Didn't try to change the layout (for reusing templates).
