No, this is a potential bug not already corrected in 1.9.18 :-(.
- You have to run applyfilter _only_ if you want to suppress articles
without bodies, e.g., you retrieve the headers from alt.comp.blind-users and
alt.comp.hello-world, after choosing the articles* and doing the body
download (fetchnews -B...), there are already the non selected headers left
without bodies.
* You cannot unselect articles :-(, so you have to be careful...

If you want to suppress those articles, the only way without writing your
own program is to run applyfilter. (fetchnews -B don't do this job!)
% applyfilter -v alt.comp.blind-users
% applyfilter -v alt.comp.hello-world
will suppress the headers articles. (Your filter file can be left void :->).
( Ah, also the .overview file is not updated :-( but you can delete it :-) )

To recompile fetchnews, you have to:
1/ Apply the patch to fetchnews.c
- Go to the source directory.
- save the mail, e.g. fetch_delaybody.patch. (do not paste, because there
are tab characters or use the switch -l...)
- apply the patch:
You will have some messages, because the patch is against 1.9.18ma4.
If there are no rejected parts, its OK.
% patch < fetch_delaybody.patch 
2/ Recompile the changed sources. (only one source file is new: fetchnews.c)
% make
This will rebuild fetchnews.
3/ Move (only) the new "fetchnews" executable into the executable directory.
4/ Then running fetchnews with delaybody=1 will work only with the -H
(header) or -B (body) options.
