overlineoverlineABC produces a double bar over ABC, but it takes up too much vertical space.

How can I make the top bar closer to the bar below it?

The overline operation inserts a kern three times fontdimen8 of the math extension font (which is also used as the rule thickness).

We can so reduce this kerning by artificially making the inner overlined box less tall by twice the applied kerning.

I took the occasion for removing the scriptspace which is added in subscripts/superscripts for the inner overline atom.

You can easily vary the command doverline by changing the vertical offset (e.g. 0.5ex).

documentclassmemoir

usepackageamsmath,tikz
usetikzlibrarycalc

newcommanddoverline[1]%
tikz[baseline=(nodeAnchor.base)]
 node[inner sep=0] (nodeAnchor) $#1$; 
 draw[line width=0.1ex,line cap=round] 
 ($(nodeAnchor.north west)+(0.0em,0.2ex)$) 
 --
 ($(nodeAnchor.north east)+(0.0em,0.2ex)$) 
 ($(nodeAnchor.north west)+(0.0em,0.5ex)$) 
 --
 ($(nodeAnchor.north east)+(0.0em,0.5ex)$) 
 ;

EDIT: egreg's solution is more concise when dealing with subscripts and superscripts. My solution could be adopted to this by using LuaTeX access to mathstyle but as his solutions already deals with this issue there is not really a need for it.

There is another solution on https://tex.stackexchange.com/a/418483/128553.
