Changed to three instead of two parameters (the first one is new):
〈env〉:=#1: (added) internal name of the theorem environment,
〈use ctr〉:=#2: internal name of the theorem which counter is used,
〈output name〉:=#3: keyword to be displayed in the output; all arguments
are transmitted from \@othm/\@xnthm/\@ynthm.
Lines 817–819: if thmmarksis active, the counter for the current environment
〈env’〉 is incremented, since the last endmark in environment 〈env’〉 is
definitely not the position for its endmark (necessary for nested environments
ending at the same time).
Line 820: set \InTheoType to 〈env〉.
Lines 821–824: ifthmmarksisactive, incrementcurr〈env〉ctrandsetend〈env〉ctr
to 0.
Line 825: adapted from latex.ltx: increment the corresponding counter.
Line 826: perform prework (before theorem structure is generated).
Line 827: call L ATEX’s original \trivlist. It does just organizational things,
no actual skips! The skip is added later when the first \item is typeset.
Lines 828–840: handle\theorempreskipamount,\theorempostskipamount,
\theoreminframepreskipamount,and\theoreminframepostskipamount
(old skip schema: if in vmode, there is additional space, cf. \trivlist
and \@trivlist in latex.ltx).
Lines 841–842: initialize \@topsep (the space before the first item) and
\@topsepadd (the space after the first item). (see explanation of spacing
in the note preceding this macro.)
Lines 843–845: handle \theoremindent.
Line 846: if there is an optional argument, call
\@ythm{〈env〉}{〈use ctr〉}{〈output name〉}, otherwise call
\@xthm{〈env〉}{〈use ctr〉}{〈output name〉}.
