improve git/gitless interaction: print git commands

I propose to add a verbose mode, where all executed git commands are printed to stderr. Most people will have to learn git eventually, because everyone around them is using plain git.

Therefore showing them the 'proper' git commands helps them understanding git and explaining to people only knowing git what is going on.

I would propose to simply add a '-v' switch. Someone who wants to have that always switched on could easily create an alias.

@kontrafiktion are you sure that gitless uses git commands and not some git library through different API?

[kontrafiktion]

it uses git and pygit2, bur even for the latter I would think that is is possible 'translate' all the calls to git commands

[techtonik]

@kontrafiktion that's a lot of work to maintain this mapping and there is no guarantee that the mapping will be correct, in case of pygit2 calls.

Just as a side note, git-town does exactly this (example) and I've found it to be pretty useful.
