borg2: check does not support custom output formatting

[tve]

Borg check doesn't seem to follow archive listing formats. I have the following format specs:

BORG_PRUNE_FORMAT='{hostname:10}{archive:>14} {time:%Y-%m-%d %H:%M:%S} {tags}'
BORG_RLIST_FORMAT='{hostname:10}{archive:>14} {time:%Y-%m-%d %H:%M:%S} {tags} {id}{NL}'

and borg repo-list prints what I expect:

tekke         daily-full 2026-02-22 17:01:01  25fb4049931884edfba23f31fb95eaf595987f2c521d3fe11207c818ac6ce38
tekke         daily-full 2026-02-22 17:01:01  2ca9d22f35cca98972a1cd12909a9e8482bb0883370632413307731521d9eb0

but borg check seems to ignore it:

Borg prune does the right thing (but adds quite some padding to the left, perhaps 'cause some other messages are longer?

BORG_RLIST_FORMAT is just for repo-list and it seems it was forgotten to rename that when rlist was renamed to repo-list.

Update: renamed the env var.

Are you planning on adding a format for borg check?

[ThomasWaldmann]

Yeah, guess that would be a good thing. But maybe we better add it after the packs feature is implemented.
