Subject: cli: propagate batch tagging warnings to exit value
X-Git-Tag: 0.15_rc1~7
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=4b5b6f02cc943b83270ad5061166e5d9967b2899

cli: propagate batch tagging warnings to exit value

In case last input for batch tagging was either invalid or skippable
line, notmuch command exited with non-zero value.
After this change if there is at least one invalid line, notmuch
command will exit with non-zero value. Additionally, skipped lines
(last or other) doesn't cause non-zero value to be returned.
