From: Abhradeep Chakraborty <chakrabortyabhradeep79@xxxxxxxxx>
`parse-options.c` doesn't check if the usage strings for option flags
are following the style guide or not. Style convention says, usage
strings should not start with capital letter (unless needed) and
it should not end with `.`.
Add checks to the `parse_options_check()` function to check usage
strings against the style convention.
