* Historically, the "Only in" messages produced in dir modemillert2003-07-211-10/+5
| | | | | | | | | were not printed when the output format was -e (ed) since this prevented the output from being used as an ed script. However, POSIX specifies that this message shall always be printed regardless of the output format (this is also what GNU diff does). Also do the same with the "Common subdirectory" message which POSIX lists as optional.
* Fix printing of status when not in -l mode which was broken when themillert2003-07-211-4/+6
| | | | -l support was added.
* Re-implement -l flag; diff -l now works correctly in non-directorymillert2003-07-091-4/+27

* Add -q option from GNU diffmillert2003-07-061-4/+4

* Implement -P from GNU diff (like -N but only for files that are missingmillert2003-07-061-14/+14

* Some fairly major changes:millert2003-07-061-303/+230
| | | | | | | | | | | | | | | | | | | | | o -N is implemented o -X is implemented o -x is implemented o diff.c has been rewritten and GNU long options are now supported o diffdir.c has been rewritten + no longer does fork + exec of /usr/bin/diff + can be called recursively (and will be for -r) o diff.h + don't include any .h files here any more, do it in the .c files + no Bell Labs code in this, gets a UCB copyright (the 32v sources only have a diff.c and there is nothing in common). o diffreg.c + most all remaining globals are now private to diffreg.c + files are only opened once + dynamically allocated objects are either freed or realloced + added missing UCB copyright (there were lots of UCB changes) + print correct thing when -s is specified OK deraadt@
