[Enhancement] Strip paths from metadata comments

[elpekenin]

Description

As per @sigprof and @tzarc discussion on discord a few weeks ago

NOTE: Does still show "fake" arguments, like --flag False (user would have used just --flag)
However, i dont think there is a great way of handling it... We may use sys.argv[1:] or the like, but that would lose some extra context/information, such as the parsing (default values? type casting?) performed by milc, while the current approach does show relevant info: what the code "sees"... Im open to other alternatives about this, anyway

Given your comment in the description about command arguments, perhaps just listing configuration items and associated value in a table?

I don't think there's a particularly large reason to keep the command listed?
