In TBC, after January 19 patch, there is a space in micromenu. Look:

Comment line 27 (_classic_\Interface\AddOns\Bartender4\MicroMenu.lua) [WorldMapMicroButton] with --  like this and it will be gone.

make sure that your version has the "LFGMicroButton", on line 28, under "WorldMapMicroButton", 

greatlabguy, Yes, my version is 4.10.10-bcc and it do have line 28 "LFGMicroButton".

NomisCode9, Thank you, that helped!

As of today's update (4.1.1.0-bcc) the space in the Micro Menu that Himitsu1990 previously mentioned has resurfaced. However, the workaround that NomisCode9 suggests doesn't apply anymore as the section of code previously altered (line 27) has been changed (see below).

local BT_MICRO_BUTTONS = WoWClassic and MICRO_BUTTONS
	or
	{
	"CharacterMicroButton",
	"SpellbookMicroButton",
	"TalentMicroButton",
	"AchievementMicroButton",
	"QuestLogMicroButton",
	"GuildMicroButton",
	"LFDMicroButton",
	"CollectionsMicroButton",
	"EJMicroButton",
	"StoreMicroButton",
	"MainMenuMicroButton",
	}
