What are the exact semantic differences between the user and emailuser template filters?
If my ~/.hgrc looks like this:
[ui]
username = First Last <first.last@gmail.com>
and then I use hg log -T {author|user} I get "first", whereas if I use hg log -T {author|emailuser} I get "first.last". Is the primary difference just how the email field is parsed, and whether non-alphabetical characters are included?
