Try to post a link to the real input. Downloading it I see no space at the line ends at all:

00000000  6d 6d 75 2d 6d 69 52 2d  37 30 34 a0 0d 0a 6d 6d  |mmu-miR-704...mm|

Which is slightly funny alright (LFA0+CRLF; thx to ikegami below), but possibly an artefact of the site markup + pasting. And probably NOT what you're using. (If I just paste from the node, I also see a trailing 0x20 space, like Corion)

also to check: how do you get the input: $temp - does it contain any LF or CR line endings?

update: also to check: char encoding of the stuff you get? cat -vet/hd/od -x might help in figuring out things (the last two being examples of those "hex dumpers" on unix or in cygwin, xxd is probably also widely available and used for vim's pseudo hex mode).
