[PATCH 2/6] difftool: remove angular brackets from argument help

["René Scharfe" <l.s.r@web.de>]

Parseopt wraps arguments in a pair of angular brackets by default,
signifying that the user needs to replace it with a value of the
documented type.  Remove the pairs from the option definitions to
duplication and confusion.
