So what are we doing for empty commands? Should we possibly just not be doing anything instead? |

I do think simply ignoring empty commands altogether should be fine, but felt it might be too big a change. Empty commands are often used to "separate" a bunch of commands from the rest for readability, or for some reason to refresh a prompt with a time indicator etc. This patch simply follows the precedent set from CMD_DURATION to fix the issue with postexec hooks receiving an incorrect duration value. If we are okay with ignoring empty commands altogether, I can just do that then. |

The weird arg length check is due to bug in fish. Sent a patch to fix it, will be released in fish 3.2.0. Ref: fish-shell/fish-shell#7085

Description
In the same vein as #4926, firing
fish_preexecandfish_postexecfor empty commands is inconsistent with the way$status,historyand$CMD_DURATIONtreat empty commands.fish_postexec, for example, receives an incorrect value for$CMD_DURATIONwhen an empty command is processed.As suggested in #4829, this patch skips firing of these events for empty commands altogether.
Fixes issue #4829
