[PATCH 0/2] bisect--helper: rewrite of check_term_format()

Important Changes:

 * The previous patch is split into two patches for a better and logical
   commit history.

 * As previously absent, strbuf is used for string manipulation.

 * This passes the complete test suite unlike the previous patches.

 * Proper use of error handling (die() and error() are used at appropriate
   places).

 * Remove the shell code which is then redundant.

 * Improve according to the minor nits given by Johannes Schindelin.

Pranit Bauva (2):
  bisect--helper: use OPT_CMDMODE instead of OPT_BOOL
  bisect: rewrite `check_term_format` shell function in C
