Be more user-friendly when refusing to do something because of conflict.
Various commands refuse to run in the presence of conflicts (commit, merge, pull, cherry-pick/revert). They all used to provide rough, and inconsistant error messages. A new variable advice.resolveconflict is introduced, and allows more verbose messages, pointing the user to the appropriate solution. For commit, the error message used to look like this: $ git commit foo.txt: needs merge foo.txt: unmerged (c34a92682e0394bc0d6f4d4a67a8e2d32395c169) foo.txt: unmerged (3afcd75de8de0bb5076942fcb17446be50451030) foo.txt: unmerged (c9785d77b76dfe4fb038bf927ee518f6ae45ede4) error: Error building trees The "need merge" line is given by refresh_cache. We add the IN_PORCELAIN option to make the output more consistant with the other porcelain commands, and catch the error in return, to stop with a clean error message. The next lines were displayed by a call to cache_tree_update(), which is not reached anymore if we noticed the conflict. The new output looks like: U foo.txt fatal: 'commit' is not possible because you have unmerged files. Please, fix them up in the work tree, and then use 'git add/rm <file>' as appropriate to mark resolution and make a commit, or use 'git commit -a'. Pull is slightly modified to abort immediately if $GIT_DIR/MERGE_HEAD exists instead of waiting for merge to complain. The behavior of merge and the test-case are slightly modified to reflect the usual flow: start with conflicts, fix them, and afterwards get rid of MERGE_HEAD, with different error messages at each stage.
