[PATCH 0/5] Documentation updates

[PATCH 0/5] Documentation updates

[David Sterba]

Formatting changes inspired by Hugo's mail and some fixes that I found along
the way. The update in Availability section removes the "heavy development &
not usable" text.

David Sterba (5):
  btrfs-progs: doc: fix argument notation and typos
  btrfs-progs: doc: remove text for unmerged features
  btrfs-progs: doc: autoformat user-supplied arguments by sed
  btrfs-progs: doc: make all commands and subcommands bold
  btrfs-progs: doc: update the Availability section
