Hi Hans,
I use your today's last TextExtract version and there is something strange
in the header templated output :
on page1 (http://www.languefrancaise.net/docs/Argot/Evaluations) I use :
{(extract 'eval_' Argot.*,-RecentChanges markup=cut
header="%rfloat%{$$pagecnt} pages sur {$$listcnt} - {$$time} %%'''Valeur
recherchée :''' {$$pattern}" unit=line prefix=link snip=%.*%)}

on page2 (http://www.languefrancaise.net/docs/Abclf/Accueil) I use :
>>bgcolor=#ffeeee<< *Chercher dans la doc locale de PmWiki (:extract
group=PmWiki* page=* name=-RecentChanges header="%rfloat%{$$pagecnt} pages
sur {$$listcnt} - {$$time} %%'''Valeur recherchée :''' {$$pattern}" regex=1
unit=line markup=cut linenum=1 pagenum=blue timer=1:) (:extractresult:) >><<

My question is about this snippet : '''Valeur recherchée :''' {$$pattern}
-on page 1 the output /Valeur recherchée :/ is in bold as expected ;
-on page 2 the output is litteraly ("include" was the targeted
pattern) : <strong>Valeur
recherchée :</strong> include
(in case the email program can't reproduce html here it is the result with
"false" _ : <_strong>Valeur recherchée :<_/strong> include)

Maybe a cosmetic bug ?
