Bug Report: Env Vars and shell functions

[Peter Bray <pbray@ind.tansu.com.au>]

Greetings,

	Can others reproduce this bug in zsh-3.0-pre2, where a command
line environment variable is ignored in other functions called by the
original functions. Very trivial double function calls seem to work
fine but some where the code in "allLogicalHosts" seems to upset the
second function call. This code has been stripped a bit but not
completely, those wish to construct a similar directory structure, can
or alternatively you can comment out the eval line and use the
explicit variable set on the line below that in "allLogicalHosts".

	History: Early beta version of zsh-2.6 ( < beta-9 ?? ) worked
but it was broken somewhere and fixed was introduced in beta-1X
according to the changelogs, unfortunately I didn't have the time to
test all the new beta versions

Regards,
Peter
