Enable future callers to report a conflict and not die immediately by
introducing a new function called error_resolve_conflict.
Re-implement die_resolve_conflict as a call to error_resolve_conflict
followed by a call to die. Consequently, the message printed by
die_resolve_conflict changes from
fatal: 'commit' is not possible because you have unmerged files.
Please, fix them up in the work tree ...
...
to
error: 'commit' is not possible because you have unmerged files.
hint: Fix them up in the work tree ...
hint: ...
fatal: Exiting because of an unresolved conflict.
Hints are printed using the same advise function introduced in
v1.7.3-rc0~26^2~3 (Introduce advise() to print hints, 2010-08-11).
