gnus-group-compact-group is an interactive compiled Lisp function in
‘gnus-group.el’.

(gnus-group-compact-group GROUP)

Compact the current group.
Compaction means removing gaps between article numbers.  Hence, this
operation is only meaningful for back ends using one file per article
(e.g. nnml).

Note: currently only implemented in nnml.
