By contrast, if you take out composite.c and > bidi.c (features XEmacs doesn't have), xdisp.c, dispnew.c, and > dispextern.h are about 40KLOC, 3X as much. Not sure it's worth to continue this line counting, but just for the record: AFAIU, you should add more XEmacs files to the "core", because xdisp.c covers some areas which in XEmacs are on separate files. For example, display of the tool bar, echo-area messages, frame titles, horizontal scrolling, glyphs, and mouse highlight are all implemented on xdisp.c. Also, about 1500 lines in xdisp.c are due to bidi support, so they should be subtracted from the Emacs numbers. I actually believe that the only meaningful comparison is if we add everything that is somehow related to display, because different architectures and modularization, as well as non-overlapping features, make it very hard to compare some arbitrary parts of the display engine.
