histedit: use better meta-variable names than VALUE in help text

Before this change hg help histedit would use the default variable label:

    --commands VALUE
...
 -r --rev VALUE [+]

With this change the text will be in the usual help text style and a bit more
explanatory:

    --commands FILE
...
 -r --rev REV [+]
