zsh-completion: Escape results for `journalctl --unit` Escape colons and backslashes in unit names. This gives correct completions for units with names like systemd-backlight@backlight:acpi_video0.service and systemd-fsck@dev-disk-by\x2duuid-...

zsh-completion: journalctl --identifier Fixes #1549.

zsh-completion: add missing -M completion for journalctl

shell-completion(zsh): journalctl's -b changes removed pointless index sort of bootids. use `compadd -a' to add each array, instead of expanding possibly hundreds of words needlessly. optional completion of -b

journalctl,zsh-completion: fix several issues in --help message text -- fix grammar and reword some descriptions for clarity -- add a useful description of what --follow does -- fix the description for --after-cursor -- properly introduce the FSS acronym for "Forward Secure Sealing" in both sections -- clarify the --disk-usage command [zj: perform similar changes to zsh completions] squash! journalctl: fix several issues in --help message text

zsh-completion: Move output modes to autoload

journalctl: add --list-boots to show boot IDs and times Suggested by David Wilkins <dwilkins@maths.tcd.ie> in https://bugzilla.redhat.com/show_bug.cgi?id=967521: > [Specific boot ID is a] bit of a palaver to obtain. I consulted the > verbose dump of the journal to discover the _BOOT_ID for the > timestamp, and then generated the journal dump for that boot using > journalctl _BOOT_ID=foo -o short-monotonic.

zsh_completion: Fix --user-unit completion _SYSTEMD_USER_UNIT in the --user-unit flag argument should instead be USER_UNIT. It should also have an optional `=` between the flag and the argument.

zsh_completion: Fix single letter args Things like -n to specify the lines to show with systemctl and journalctl accepts syntax like: journalctl -n4 systemctl -n14 Previously, typing `-nXX <tab>` where XX is a number, zsh would try to complete an integer. Now it will see the XX and use the _journalctl_none completion. This is also how any of the single letter options that take arguments work as well.

zsh_completion: Correctly display journal fields Show equals and field values when used with _journal_none, don't show anything if we're not using _journal_none.

zsh_completion: Speed up noncached perf of _journalctl Splitting things unnecessarily at newlines causes tab completion to take an extremely long time. Also add a note saying that caching is not good for journalctl's completion.

zsh_completion: Fix journalctl's --boot Actually displays a list of boot ID's and offsets to the user

zsh_completion: Split out zsh _journalctl Re-ordered some of the options and added a few that were missing previously as well.
