'lib-src/etags src/category.c -u -o TAGS' results in having only Dmitry> that file's tags inside TAGS (before, it contained the entries for all Dmitry> .c files). This behavior contradicts the help and stops the rest of my Dmitry> testing in its tracks. Another bug on my part, I think I've fixed it now. The next question for you is how you want it to work. Right now there are two modes: * The old mode (but with the possibility of -u) * --find mode -- which implies -u. The .etags file is only read in find mode. My idea for this code was to use locate-dominating-file to find the .etags file and just run "etags --find" from there on save. However I know you'd like to use git ls-files, and maybe other things -- you mentioned correctly handling file deletions. Tom
