Typing alias in bash list all configured alias in .bashrc

Added a new alias to open gitk with dangling commits

alias dangcom='gitk --all --date-order '$(git fsck --no-progress --no-reflogs | \grep 'dangling commit' | \gawk '{printf $3; printf " "}')''

References:

• https://sethrobertson.github.io/GitBestPractices/ (adapted the original alias from this blog post)

With adaptation coming from:

• https://stackoverflow.com/questions/2021982/awk-without-printing-newline
• https://askubuntu.com/questions/705470/lazy-calculation-result-of-bash-functions-in-alias
• https://stackoverflow.com/questions/13260969/prevent-bash-alias-from-evaluating-statement-at-shell-start

The drawback of this alias is that it gets expanded on shell starts - so, if a new dangling commit was created after the shell started, a new shell must be opened to get the full list of dangling commits.

In this last version, I updated a custom designed prompt configuration, triggered by a need from using Poetry and its custom shell.
