N? and `info PKG` now print three lines, none indented:
PKG: <description>
reason: explicitly installed | installed as a dependency | unknown | not installed
required by: <installed dependents, comma separated> | nothing
The reason comes from a new <be>_reason backend function: apt-mark
showauto / showmanual (dpkg decides for a package in neither list), the
Install Reason of pacman -Qi, dnf repoquery --installed %{reason} (dnf4
and dnf5 words) and the Installed line of zypper info (rpm plus libzypp's
AutoInstalled when zypper is locked). A row whose old version is "-" is
not installed and the backend is not asked. The "(installed)" qualifier
moves to --help, README and DESIGN.
The rpm E2E fixture and e2e_reset now also mark su-dummy-a and su-dummy-c
as user-installed on dnf, which records plain rpm installs as "unknown",
so 1? and 2? show both reasons on all 12 distros. The verified commands
are recorded in discovery/{apt,pacman,rpm}.md.

|
|
# FAKE_APT_MARK_UNHOLD_SIGNAL=SIG: send SIG to the applet before an unhold (a second Ctrl-C).
|
|
# FAKE_APT_MARK_UNHOLD_RC=N: unhold fails (nothing released). FAKE_APT_MARK_FAIL_MSG: the message a

# failing hold prints. Every unhold logs whether $STATE_DIR/holds.lock is held by someone.

# showauto/showmanual: installed = the "?i" rows of data/apt/dpkg-status.tsv (not purged), auto = those
|
|
# listed in data/apt/auto.txt, manual = the others; FAKE_APT_MARK_NEITHER="pkg ..." are in neither
|

# list, FAKE_APT_MARK_SHOW_RC=N makes both fail. Like the real ones they print only the named
