fish_prompt.fish

# Based on top of fish's built-in "informative" shell style (see fish_config)
# I actually forgot what it's called exactly
#
# Most is the same. Only thing different is that it:
# - prints leading space because my head is tired from moving to the left in
#   internet articles, terminal programs, and prompt
# - changes the suffix to ">"
# - fixes git clean state char
# - makes base name blue
# - print user@hostname in right prompt (see fish_right_prompt)
