Comma in snippet filename

[James Lowe]

Hello,

I noticed an .ly file called

'conducting-signs,-measure-grouping-signs.ly'

In my most recent download of the source.



The snippet text in rhythms.itely matches

> @lilypondfile[verbatim,lilyquote,ragged-right,texidoc,doctitle]
> {conducting-signs,-measure-grouping-signs.ly}

I didn't want to touch this as I don't pretend to understand the 
implications of this but nothing else has a comma in the snippet dirs.

Could this cause any problems for builds?

James
