sequencer: avoid garbled merge machinery messages due to commit labels
sequencer's get_message() exists to provide good labels on conflict hunks; see commits d68565402a ("revert: clarify label on conflict hunks", 2010-03-20) bf975d379d ("cherry-pick, revert: add a label for ancestor", 2010-03-20) 043a4492b3 ("sequencer: factor code out of revert builtin", 2012-01-11). for background on this function. These labels are of the form <commitID>... <commit summary> or parent of <commitID>... <commit summary> These labels are then passed as branch names to the merge machinery. However, these labels, as formatted, often also serve to confuse. For example, if we have a rename involved in a content merge, then it results in text such as the following: <<<<<<<< HEAD:foo.c int j; ======== int counter; >>>>>>>> b01dface... Removed unnecessary stuff:bar.c Or in various conflict messages, it can make it very difficult to read: CONFLICT (rename/delete): foo.c deleted in b01dface... Removed unnecessary stuff and renamed in HEAD. Version HEAD of foo.c left in tree. CONFLICT (file location): dir1/foo.c added in b01dface... Removed unnecessary stuff inside a directory that was renamed in HEAD, suggesting it should perhaps be moved to dir2/foo.c. Make a minor change to remove the ellipses and add parentheses around the commit summary; this makes all three examples much easier to read: <<<<<<<< HEAD:foo.c int j; ======== int counter; >>>>>>>> b01dface (Removed unnecessary stuff):bar.c CONFLICT (rename/delete): foo.c deleted in b01dface (Removed unnecessary stuff) and renamed in HEAD. Version HEAD of foo.c left in tree. CONFLICT (file location): dir1/foo.c added in b01dface (Removed unnecessary stuff) inside a directory that was renamed in HEAD, suggesting it should perhaps be moved to dir2/foo.c.
