// Add a "# [TICKET-ID]" comment hint to the editor when running a plain
|
|
// `git commit` on a branch containing a ticket ID (e.g. buddy/BE-1234/foo,
|
|
// fix/BE-1234/bar). The hint is a comment, so git strips it unless you
|

// uncomment or retype it.

// Every other way a commit message gets made is left alone: -m/-F
|
|
// ("message"), merge, squash, amend/-c ("commit"), and commit templates
|
|
// ("template") all arrive with a mode argument, and we exit immediately.
