[Plugin: Simple Footnotes] Unwanted space before note in post text

Hi Andrew — thanks for making this plugin. Very clean, no-muss-no-fuss. 🙂

There is just one little tiny thing: the footnote numbers were appearing in my text with an extra space before them that I don’t want.

Example (number sign indicates the linked, superscripted footnote number):

Lorem ipsum.[ref]My note, etc.[/ref] Blah blah blah, and so forth.
produces

Lorem ipsum. # Blah blah blah, and so forth.

I fixed this by changing the beginning of line 75 of simple-footnotes.php from this:
return ' <a class="simple-footnote"
to this:
return '<a class="simple-footnote"

I’m aware, however, that this change will be wiped out by an update of the plugin. I don’t know if you put the leading space before the inline citation number there on purpose.

My humble request is that if you prefer to leave it as-is by default, could there be an option for the user to eliminate the leading space?

Thanks again –
Derek
