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.
