I don't agree this should be changed. The repetition helps improve
understanding because not everyone would assume that a METAVAR shown once would
automatically also apply to its long form.
Also, showing the METAVAR more than one is a norm. For example, see this
excerpt from "man grep":
-B num, --before-context=num
Print num lines of leading context before each match. See also
the -A and -C options.
-b, --byte-offset
The offset in bytes of a matched pattern is displayed in front of
the respective matched line.
-C[num, --context=num]
Print num lines of leading and trailing context surrounding each
match. The default is 2 and is equivalent to
-A 2 -B 2. Note: no whitespace may be given between the option
and its argument.
-c, --count
Only a count of selected lines is written to standard output.
--colour=[when, --color=[when]]
Mark up the matching text with the expression stored in GREP_COLOR
environment variable. The possible values of
when can be `never', `always' or `auto'.
-D action, --devices=action
Specify the demanded action for devices, FIFOs and sockets. The
default action is `read', which means, that
they are read as if they were normal files. If the action is set
to `skip', devices will be silently skipped.
-d action, --directories=action
Specify the demanded action for directories. It is `read' by
default, which means that the directories are read
in the same manner as normal files. Other possible values are
`skip' to silently ignore the directories, and
`recurse' to read them recursively, which has the same effect as
the -R and -r option.
