#359: regsub documented as using $1,$2 etc, but actually uses \1, \2 for
replacement strings

--------------------+-------------------------------------------------------
 Everywhere I've seen in the documentation, it says that $1,$2 etc are used
 for replacement strings in regsub, e.g.

 set bereq.url = regsub ( req.url , "/from_dir/(.*)" , "/to/url=$1" );

 However, this just results in a literal '$1' inserted.  In fact \1,\2 etc
 are used, so it should be

 set bereq.url = regsub ( req.url , "/from_dir/(.*)" , "/to/url=\1" );

 This can be confusing, and should be fixed at some point.
