Instead of outputting the full SHA1 values of object names try to
abbreviate them to a shorter unique name. When no length is specified
used immediately following a ref name and the ref must have an
existing log ($GIT_DIR/logs/<ref>).
+* A ref followed by the suffix '@' with an ordinal specification
+ enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
+ the n-th prior value of that ref. For example 'master@\{1\}'
+ is the immediate prior value of 'master' while 'master@\{5\}'
+ is the 5th prior value of 'master'. This suffix may only be used
+ immediately following a ref name and the ref must have an existing
+ log ($GIT_DIR/logs/<ref>).
+
+* You can use the '@' construct with an empty ref part to get at a
+ reflog of the current branch. For example, if you are on the
+ branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
+
* A suffix '{caret}' to a revision parameter means the first parent of
that commit object. '{caret}<n>' means the <n>th parent (i.e.
'rev{caret}'
and dereference the tag recursively until a non-tag object is
found.
+* A colon, followed by a slash, followed by a text: this names
+ a commit whose commit message starts with the specified text.
+ This name returns the youngest matching commit which is
+ reachable from any ref. If the commit message starts with a
+ '!', you have to repeat that; the special sequence ':/!',
+ followed by something else than '!' is reserved for now.
+
* A suffix ':' followed by a path; this names the blob or tree
at the given path in the tree-ish object named by the part
before the colon.
A similar notation "`r1\...r2`" is called symmetric difference
of `r1` and `r2` and is defined as
"`r1 r2 --not $(git-merge-base --all r1 r2)`".
