fish: improve formatting of help text of generated commands

Browse Source 
In the generated description of the guestfish commands, wrap and indent
the help text, so it is a multiline string instead of a very long single
one.

This has no behaviour changes, only makes cmds.c more readable (and
easier to diff when the description of actions change).
