Summary: wxFileConfig::DeleteGroup not reacting as expected

Initial Comment:
Please find the proof of concept attached hereby (against minimal sample).

Basically it is if you do a DeleteGroup on a wxFileConfig, and then add new items into the just deleted group, that you get rather weird results.

Expected results:

Step 1:
[Config]
A=1
[User]
U0=test-value
U1=test-value
U2=test-value
U3=test-value
U4=test-value

Step 2:
[Config]
A=1

Step 3:
[Config]
A=1
[User]
U0=test-value2

==> Step 3 gives:
[Config]
[User]
U0=test-value2
A=1



Greetz,
Steven

Investigating more it seems it's going wrong somewhere here:

wxFileConfigLineList *wxFileConfigGroup::GetLastEntryLine()
-> There it thinks it doesn't have a LastEntryLine (which it should have,
namely A=1), so it adds the line "[User]" directly under the "[Config]"
header.

It seems this works perfect if the file doesn't exist first, but if you do
this on an already existing file, you get this erroneous behaviour.
