True, and I added that mistake a while ago.  Oops.

Subject: [PATCH 9/8] run-command: fix return value comment

483bbd4e4c (run-command: introduce child_process_init(), 2014-08-19) and 2d71608ec0 (run-command: factor out child_process_clear(), 2015-10-24) added help texts about child_process_init() and child_process_clear() without updating the immediately following documentation of return codes that only applied to the preexisting functions.

4c4066d95d (run-command: move doc to run-command.h, 2019-11-17) started to list the functions explicitly that this paragraph applies to, but still wrongly included child_process_init() and child_process_clear(). Remove their names from that list.
