My tests on Windows 10 indicate that lilypond.exe can't handle UNC
notation.  This is true even of a local file.

First I "type" the file (Windows version of "cat") and it works fine with
UNC.  Then I try to launch LilyPond with the same file name and it can't
find the file.

*** Start command line
C:\Users\Knute\Desktop
>type \\KNUTE-HP\Users\Knute\Desktop\test.ly
\version "2.19.81"

{ c'4 d' e' f' }
C:\Users\Knute\Desktop
>lilypond \\KNUTE-HP\Users\Knute\Desktop\test.ly
GNU LilyPond 2.19.81
warning: cannot find file: `\\KNUTE-HP\Users\Knute\Desktop\test.ly'
fatal error: failed files: "\\\\KNUTE-HP\\Users\\Knute\\Desktop\\test.ly"
*** End command line
