For the general case, you may want to suggest that the maintainer include
instructions about this in each upgrade notice, but nothing should be done in
the package as it assumes too much about users' environments.

For example: what if their default shell/s is/are not bash, or they don't
already have a .bashrc, and shouldn't you do that setup in whatever their shell
profile is, if they have one, and what if they don't; what if Pageant or Cygwin
don't use Cygwin /tmp/ but some other TMPDIR e.g. Windows ~/AppData/Local/Temp/;
what if your users run ssh from cmd without starting Cygwin; etc.?

You may do what your users allow you on their systems, but you have to ensure
that your Putty/Pageant and ssh setup additions work flawlessly on all of them,
coordinating between what you do for Pageant and what you do for ssh.

You may want to consider doing whatever is required in each user's ssh_config if
possible, or /etc/ssh_config to provide users defaults, as those depend least on
each user's environment.
