Consider using includeIf in Git config

[wincent]

I don't think I'll do this, but I at least wanted to mention it as a possibility.

Variables that I currently set differently on my work vs personal machines:

wincent/aspects/dotfiles/index.ts

Lines 57 to 61 in e2d1b9d

	gitGpgSign: identity === 'wincent' && profile !== 'codespaces',
	gitHostSpecificInclude: `host/${hostHandle}`,
	gitUserEmail: identity === 'wincent' ? '[email protected]' : '',
	gitUserName: identity === 'wincent' ? 'Greg Hurrell' : '',
	gitHubUsername: identity === 'wincent' ? 'wincent' : '',

Via host-based includes:

• On Codespaces, I set user.email to [email protected].
• Likewise, on my work laptop I set user.email to [email protected].
• On my personal machines I set some sendmail.* settings.

Additionally:

• When the gitGpgSign variable is set (ie. everywhere except Codespaces) I set commit.gpgSign to true.
• When gitHubUsername is set (always, for me) I set github.username to wincent.
• I set user.name and user.email based on the value of the gitUserName and gitUserEmail variables, respectively; these default to Greg Hurrell and [email protected], except as noted above.

The idea, then, is to use includeIf to set up some config for work repos whenever the remote URL includes github.com/github/. This might replace, in whole or in part, the host-specific config includes.

Now, the main reason why I think I'm not going to do this is it doesn't jive well with my GPG signing strategy (which is to keep a work key on my work machine, and a personal key on my personal machines). Because the work machine only has the work key, if I go into a personal repo like my dotfiles and set things up to use my personal email, I won't be able to sign the commits any more. I think I could set it up to turn off signing in that case, but do I want to? I don't think it's worth it. Likewise, I don't like the security trade-off of putting a personal GPG key on a work machine. So, all of this is a long-winded way of saying that I don't think I'm going to do this, but I wanted to document the possibility anyway.
