[Wine-patches] [eter-2.1 2/2] msi: Correctly parse double quotes in the token value. (eterbug #8375).

[Dmitry Timoshkov]

This fixes an installer that passes to InstallProduct a command line like
PROPERTY1="Installing ""Product name"" version 8.0" PROPERTY2=1 PROPERTY3=1
In this case properties PROPERTY2 and PROPERTY3 were not recognized and that
led to an installation failure when a custom action didn't see them as set.
