Perl: Textmode vs. Binary mode...

I stumbled into the same problem a wile ago and tried exactly this
solution, but it didn't work. The reason is, that the $ in the RE
matches (perldoc perlre):

    $   Match the end of the line (or before newline at the end)

so the line ending \n will not be removed. I ended up with

    s/[\r\n]+\z//;      # remove CR and/or LF at the end of $_

(and some time later replaced it with

    s/\s+\z//;          # remove whitespace at the end of $_

but that may not be what you want.)
