contrib: add editmerge script for editor conflict prompts
Adds a script that opens the editor to the conflict as part of the merge
process. This way you can fix the merge during the rebase instead of having to
pause the rebase, resolve --mark, rebase --continue.
Only works on unix.
$ hg init
$ echo 123 > a
$ hg add a
$ hg commit -m "first" a
$ mkdir sub
$ echo 321 > sub/b
$ hg add sub/b
$ hg commit -m "second" sub/b
$ cat sub/b
321
$ hg co 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ cat sub/b 2>/dev/null || echo "sub/b not present"
sub/b not present
$ test -d sub || echo "sub not present"
sub not present
