>Description:
In some INF files, we can meet some texts to define a register key like below
"ENUM\"%ZD1211B_50U_PNP%
It makes a ndiscvt(8)'s syntax error when it parses because \" is treated as a character escape sequence.
>How-To-Repeat:
$ cat > t.inf
[UnZDRegistryUSB.reg]
HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\UNZD1211B%InterfaceType%,DEL_HKR_0000,0,"ENUM\"%ZD1211B_50U_PNP%
^D
$ ndiscvt -i t.inf -s ZD11BUXP.SYS -o tmp.h
ndiscvt: line 2: %ZD1211B_50U_PNP%: syntax error.
