Empty UnparseableSections is not marked as rawBody

[frankkopp]

Describe the bug
When loading an ini with multiple sections with the last section as "UnparsableSection" and this last section is empty then the Section is not marked as rawBody and therefore can not be used to write raw data to.
It works well when at least one line of data is in the section.

To Reproduce
Loading:
tmpIni, err := ini.LoadSources(ini.LoadOptions{ UnparseableSections: []string{"customData"}, }, *c.IniFileName)

INI-file:
[customData]

Same code but with at least one line in the section:

Expected behavior
Every section marked with UnparseableSections should be a "rawBody" section. Even if it is empty

Screenshots
See above

Here is the piece in your code were it goes wrong:

The line 481: section.isRawSection = true is only executed after reading the the next line. If the file is at it's end it will never be set.

Maybe move this line as per my suggestion in the screenshot?
