The value of the user-login-name variable should be the same as the
result of the user-login-name function; is it?

Again, see the corresponding function:

,----[ C-h f user-real-login-name RET ]
| user-real-login-name is a built-in function.
| (user-real-login-name)
|
| Return the name of the user's real uid, as a string.

My guess is that you logged in as root, then su'ed to pranav without the
- argument.

No, it's more complicated than that.  It gets set to t by the
command-line function in startup.el, then reset either to the actual
file name (by a call to load) or to nil (if load can't find the file).

It's not, see the command-line function in startup.el.
