Option sort in usage help should ignore prefix #697
Description
Currently, options that only have a long name (and do not have a short name) are always shown before options with a short name. For example:
Usage: git commit [--squash=<commit>] [-m=<arg0>] [<file>...]
[<file>...]
--squash=<commit>
-m, --message=<arg0>
Instead, they should be inserted in the list by their first non-prefix letter.
Should be:
Usage: git commit [-m=<arg0>] [--squash=<commit>] [<file>...]
[<file>...]
-m, --message=<arg0>
--squash=<commit>
