[kde-doc-english] subpatterns in regexp replacement text

Hi,
I'd like to suggest that in the regexp section of the Kate docs
(http://www.kate-editor.org/doc/regex-patterns.html), you mention, or
even emphasize, that you can reference subpatterns in the replacement
text. This a is a very powerful feature which is absolutely necessary
for doing certain kinds of replacements, and so might even warrent its
own subsection.
For example, find
PROBLEM ([0-9]+)
and replace with
<bold>PROBLEM \1</bold>
I make this suggestion after I went looking for this in the kate
documentation. I've done this before with other regexp tools but
couldn't remember the syntax. I couldn't find it, and ended up looking
it up in some other (non-Kate) regexp writeup and the syntax I found
worked. Looking at the documentation again, I think the Sub Patterns
section essentially explained the basic feature, just not in the context
of replacement, or mentioning that this was possible at all. Perhaps a
section dedicated to what you can do with the replacement text would be
the place for this.
Cheers,
Eric
