-# The file into which is accumulated the suggested commit message for
-# squash/fixup commands.  When the first of a series of squash/fixups
-# is seen, the file is created and the commit message from the
-# previous commit and from the first squash/fixup commit are written
-# to it.  The commit message for each subsequent squash/fixup commit
-# is appended to the file as it is processed.
-#
-# The first line of the file is of the form
-#     # This is a combination of $count commits.
-# where $count is the number of commits whose messages have been
-# written to the file so far (including the initial "pick" commit).
-# Each time that a commit message is processed, this line is read and
-# updated.  It is deleted just before the combined commit is made.

-# If the current series of squash/fixups has not yet included a squash
-# command, then this file exists and holds the commit message of the
