[Modules] PATH grows by @bindir@ every time modules is initialized

[Martin d'A. <mar...@gm...>]

Hi,

My PATH keeps growing with the same value of @bindir@ over and over when
modules is repeatedly initialized, and I suspect that the code below is the
reason. So inside modules-tcl/init/bash.in, I would like to know the purpose
of this code
<https://github.com/cea-hpc/modules/blob/c1fd4dc12f591bb877f392d7307151640573d443/init/bash.in#L68-L72>
:

@setbinpath@ if [[ ! ":$PATH:" =~ ':@bindir@:' ]]; then
@setbinpath@@prependbinpath@ PATH=@bindir@${PATH:+:}$PATH
@setbinpath@@appendbinpath@ PATH=$PATH${PATH:+:}@bindir@
@setbinpath@ export PATH
@setbinpath@ fi

Thanks,
Martin
