#4 fail with symbol "`" in filenames

[Mihail Kasadjikov]

If filenames contains symbol "`" (code 0x60) then program will fail with this message:

$ burn-cd-1.8.0 -s 2 -l "X-Files 3" *.avi
* Checking programs... [ok]
* Unmounting device /dev/sr0... [ok]
* Looking for a disk in drive... [ok]
* Checking disk type... [ok]
* Calculating new session size... sh: -c: line 0: unexpected EOF while looking for matching ``'
sh: -c: line 1: syntax error: unexpected end of file
[something wrong]

It happens because the symbol "`" have to be escaped. I have created simple patch to fix this problem (see attachment).
