'git branch' has an option to edit a branch's description, but lacks
the option to show that description.
Therefore, add a new '--show-description' option to do just that, as a
more user-friendly alternative to 'git config --get
branch.$branchname.description':
- it's shorter to type (both in the number of characters and the
number of TABs if using completion),
- works on the current branch without explicitly naming it,
- hides the implementation detail that branch descriptions are
stored in the config file, and
- errors out with a proper error message when the given branch
doesn't exist (but exits quietly with an error code when the
branch does exit but has no description, just like the 'git config'
query does).
+test_expect_success '--show-description with no description errors quietly' '
+ git config --unset branch.master.description &&
+ test_must_fail git branch --show-description >actual 2>actual.err &&
+ test_must_be_empty actual &&
+ test_must_be_empty actual.err
+'
Checking the exact contents of stderr typically fails when tests are run
under -x. Perhaps
test_i18ngrep ! "fatal: " actual.err &&"
test_i18ngrep ! "error: " actual.err &&
test_i18ngrep ! "warning: " actual.err
Which makes me wonder: Why would --show-description have to error out
silently? This is not 'git config' after all.
