[PATCH v5 0/2] name-rev: deprecate --stdin in favor of --annotate-stdin

Introduce a --annotate-stdin that is functionally equivalent of --stdin. --stdin does not behave as --stdin in other subcommands, such as pack-objects whereby it takes one argument per line. Since --stdin can be a confusing and misleading name, the goal is to rename it to --annotate-stdin.

This is the first step in a process of eventually fully deprecating --stdin. This change also adds a warning to --stdin warning that it will be removed in the future.

See https://lore.kernel.org/git/xmqqsfuh1pxz.fsf@gitster.g/ for discussion.

changes since v4:

 * fixed documentation example indentation

changes since v3:

 * use strbuf_getline instead of strbuf_getwholeline (based on Junio's
   feedback)
 * fixed commit message s/annotate-text/annotate-stdin (based on Junio's
   feedback)
 * since strbuf_getline does not keep the trailing terminator, add back '\n'
   with strbuf_addchr
 * reordered documentation blocks based on (Philip Oakley's feedback)
 * fixed doc typos in example block
