Hi fellow Monks,

this one has me baffled...

I have the following code which reads files like http://oss.sgi.com/projects/ogl-sample/registry/APPLE/client_storage.txt

sub read_spec($)
{
    my $filename = shift;
    local $/;
    open(my $fh, "<$filename") or die "Can't open filename";
    my $content = <$fh>;

    $content =~ s{\s+$}{}m;

    # ...
}

[download]

If you take a look at the file I mentioned above, you'll notice it has this:

Name

    APPLE_client_storage
<tab here>
Name Strings
...

Running the above code on this file leaves the tab character in place.

Adding:

    $content =~ s{\s+$}{}m;
    $content =~ s{\t+$}{}m;

[download]

has the desired effect. As well as this:

    $content =~ s{[ \t]+$}{}m;

[download]

Ideas? My understanding of \s is flawled somewhere. After following manpages around, is ended up in isspace(3), which makes me beleive that the code should work as I expect it to.

Update: Fixed formatting...
