#  Call ps1_update within your PROMPT_COMMAND
#
# The PROMPT_COMMAND is used to help the prompt work if the separator is not a new line.
# In the event that the separtor is not a new line, the prompt line may become distored if
# you add or delete a certian number of characters, making the string wider than the
# $COLUMNS + len(your_input_line).
# This orginally was done with callbacks within the PS1 to add in things like the git
# commit, but this results in the PS1 being of an unknown width which results in the prompt
# being distored if you add or remove a certain number of characters. To work around this
# it now uses the PROMPT_COMMAND callback to re-set the PS1 with a known width of chracters
# each time a new command is entered. see PROMPT_COMMAND for more details.
