[PATCH v4 1/2] amend remaining usage strings according to style guide

["Abhradeep Chakraborty via GitGitGadget" <gitgitgadget@gmail.com>]

From: Abhradeep Chakraborty <chakrabortyabhradeep79@gmail.com>

Usage strings for git (sub)command flags has a style guide that
suggests - first letter should not capitalized (unless required)
and it should skip full-stop at the end of line. But there are
some files where usage-strings do not follow the above mentioned
guide.

Amend the usage strings that don't follow the style convention/guide.
