patch fixing profile writing

[mehmet yasar <myasar@free.fr>]

it may not be the best solution ...

Bug Description:
Reading an ini file works perfectly but whenever a key is modified
the file written is incorrect (since this forces flushing to disk) :
the actual code adds empty sections ([]) to the file.

Cause: (see wine/files/profile.c):
The first section created by PROFILE_Load() (which reads the
ini file) is an empty one (first_section->name[0]=0), and PROFILE_Save()
saves this to disk.

Remedy:
Do not save empty sections :

         for (key = section->key; key; key = key->next)
         {
             fprintf( file, "%s", key->name );

Remark:
Win2K and Win98 allows the creation of empty sections ([]), this is not
handled by my patch nor by the actual version of wine (bugguy).
I have not seen any application relying on this feature ...

Thanks,
