"Login" can refer to credentials used for authentication, or the processes of authenticating, but it is incorrect to use it as a verb, e.g. "I will login to this system". Unfortunately, we have a number of places where we incorrectly use "login" as a verb.
Now at least the TAG uses "login" and "log in" correctly.
Changed from "login" to "log in" where appropriate in our tlclient code. Looked at attachment 1241 [details], everything on the topic of "login is not a verb" has been patched. Leaving the other changes, "auto" -> "automatic", for now since it is not within the scope of this bug.
I found one instance of this in upstream TigerVNC, PR: https://github.com/TigerVNC/tigervnc/pull/1864
I also found a few instances of this in our openssh, PR: https://github.com/openssh/openssh-portable/pull/532
Checked native client for incorrect "login" vs. "log in" usage. Everything seems to be in order.
The fix in commit r41296 looks good. Also checked and fixed in vsm for incorrect "login" vs "log in" in commit r41303.
