use script output as regex pattern in folder-fook

[Steve S <elcorto@xxxxxxx>]

Hi

I have a folder-hook acting on different folders:

    folder-hook folder1|folder2|folder3 ...

I replaced this with

    folder-hook script.sh| ...

and script.sh :

    echo 'folder1|folder2|folder3'

Now, the pattern matches every folder, i.e. the hook acts on all folders, not
just folder1,2,3. Is there a way do actually see what Mutt gets if it executes
script.sh (there's nothing in .muttdebug0)? Or doesn't the script get executed
at all.
