Filenames with periods before .ly extension break ly2dvi

[David Petrou]

Normally I can do "ly2dvi my_music" when the full filename is
"my_music.ly".  But, I tried "ly2dvi super-staff.eg" when the full
filename was "super-staff.eg.ly" and got the following:

ly2dvi (GNU LilyPond) 1.3.124
executing: lilypond  super-staff.eg 2>&1
GNU LilyPond 1.3.124.
warning: can't find file: `init.eg'

ly2dvi Hmm, I could not find an output file name

Rerunning with "ly2dvi super-staff.eg.ly" worked fine.
