dash is usually used for representing stdin / stdout as a file. I
think this could drive to error... but I would agree with transforming
-h1 to @{-1} or -h2 to @{-2} (-h representing head).
I do agree however that all those signs are thought with american
keyboards in mind. All those punctuation marks are usually hard to
type in other keyboards, and -h1 is way simpler than HEAD~ or @{-1}
This links provides an example of my worry:
