$ man bash
/--login

--8<----
       --login
              Equivalent to -l.

<SNIP>
       --noprofile
              Do  not read either the system-wide startup file /etc/profile
or
              any  of  the  personal  initialization  files
~/.bash_profile,
              ~/.bash_login,  or  ~/.profile.   By  default,  bash reads
these
              files when it is  invoked  as  a  login  shell  (see
INVOCATION
              below).
--8<----

Looks like W.P's bash acts as a login shell by default. Maybe it is compiled
that way, or "bash" might be a (sym)link or something?
