2.43

- fixed rt.cpan.org#40925, $indichar replaced by internal
	  configuration variable EOFseparator, which contains
	  a 256 bit SHA checksum of the date I fixed the bug.
	  This will prevent future conflicts hopefully. In addition
	  it makes it possible to make it customizable, if neccessary,
	  in a future release.

	- fixed rt.cpan.org#42721, return undef for empty values

	- fixed rt.cpan.org#42331, return undef for empty objects

	- fixed rt.cpan.org#44600, comments after blockname
	  causes parser failure.

	- fixed rt.cpan.org#42287, whitespace at beginning or end
	  of a quoted value gets lost after save().

	- fixed rt.cpan.org#46184, variables that were not previously
	  defined are deleted when -InterPolateEnv is enabled. 

	- fixed bug in config loader for FileHandle objects, it
	  supports now any compatible object. Hint by Ingo Schmiegel.

	- applied spelling- and speedup patches by Ville Skyttä.

	- applied documentation patch by Jordan Macdonald.
