Subject: lib: add NOTMUCH_STATUS_PATH_ERROR
X-Git-Tag: 0.21_rc0~96
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=b59ad1a9cc6ea03764b1cd3d038920581ac5a9c4

lib: add NOTMUCH_STATUS_PATH_ERROR

The difference with FILE_ERROR is that this is for things that are
wrong with the path before looking at the disk.

Add some 3 tests; two broken as a reminder to actually use this new
code.
