mergetools: vimdiff issue a warning explaining how to abort
Adds a message displayed at each vimdiff invocation:
merge conflict detected, type ":cq" to abort
Vimdiff is very confusing for non-vim user (not to speak about vim user confused
anyway. However it is very likely that vimdiff is picked as the mergetool of
choice when using the default config:
- vim is available on all UNIX system.
- Its one of the rare non graphical merge tools.
