-- indenter and prettifier
fish_indent is used to indent a piece of fish code. fish_indent reads commands
from standard input and outputs them to standard output.
The following options are available:
- -i or --no-indent do not indent commands; only reformat to
one job per line
- -v or --version displays the current fish version and then
- --ansi colorizes the output using ANSI escape sequences,
appropriate for the current $TERM, using the colors defined in the
environment (such as $fish_color_command).
- --html outputs HTML, which supports syntax highlighting if
the appropriate CSS is defined. The CSS class names are the same as the
variable names, such as fish_color_command
