Ok, I will remove that in my next commit.

I agree, stiked-though sounds to me like an horizontal strike, but not
being a native speaker, I have not any idea if my impression is right.

Ok, I will remove « text », I think that the intention was to mean that
in Greek text (not math formula) the epsilon used looks more often like
\epsilon than like \varepsilon. That is why I had proposed rephrasing
like « lower case Greek letter (ordinary). Looks like Greek-text
letter. »

Please note that in some other part of the node (namely the « \in »
entry), it is termed as « rounded small epsilon ».

As I had already mentioned the word « curly » (« bouclé » in French)
does not sound right to me either, because \varepsilon is not curly
enough for « bouclé » to make it. Neither does « small and rounded »
(« petit et arrondi » in French) because the lunar epsilon is also small
& rounded, so that is not distinctive. That is why I have written « en
forme de 3 retourné », (ie « shaped like a flipped 3 »). Maybe instead
of « retourné » (ie « flipped ») « culbuté » (ie « rotated 180° ») would
be better. Another idea would be « avec une paire de fesses » (ie « with
a pair of buttocks ») or just « fessu » (« buttocked ») --- but not sure
if this wording is OK for everybody, at least it has the merits to be
funny.
