Patch 1/2 for SmartForms Installer: PROFILE_GetString incorrect return value

[Joshua Thielen <thielen@netprince.net>]

This patch fixes an error encountered in the Smart Forms installer 
(somewhat related to bug 575).

When calling GetPrivateProfileString with the second parameter as NULL, 
all of the keys under the specified section are copied to the buffer. 
The return value should be the number of characters copied minus the 
last null terminator. Since the keys are copied as null-terminated 
strings with the last string terminated with two null characters, strlen 
cannot be used to determine the number of characters copied. This patch 
corrects PROFILE_GetString for this case.
