histedit: temporarily shorten name of 'constraints' variable

An upcoming changeset will make the line where this variable is used
slightly too long. Other later changesets will clean that up further and makes
the variable unnecessary, so this is only temporary and it does seems useful to
put anything more complicate in place.
