[PATCH v6 0/3] bisect--helper: check_term_format() & write_terms()

[Pranit Bauva <pranit.bauva@gmail.com>]

To show how I am going to approach conversion of shell function to its C
implementation by using the subcommand/cmdmode approach, I have first converted
check_terms_format() to a subcommand then I have converted write_terms() to
a subcommand and then remove the subcommand for check_terms_format() and
instead call that function from write_terms().

Also I investigated about the test coverage which I mentioned in my previous
version and there is nothing that could be done to improve it.

Minor changes wrt v5:
 * Use the term cmdmode instead of subcommand as pointed out by Junio. (I
   didn't understand his response in v4 then Christian and Johannes pointed
   it out to me what he meant).
 * Move the enum cmdmode (for subcommand) to function scope as suggested by
   Johannes Schindelin.
 * A few minor nits by Eric Sunshine.
