 Log Message:
 [Prereq for PR bin/58609] Add EL_GETENV to libedit
 
 When interacting with the shell, and perhaps other applications,
 editline needs to obtain the values of some environment variables.
 
 Normally getenv(3) does that - but that doesn't work when being
 used in sh(1) as getenv() simply accesses the environment as it
 was when sh(1) was invoked - after that, in sh anyway, that
 environment is simply abandoned (well, kind of) - but certainly
 no changes made by the shell will be reflected there.
 
 To allow editline to obtain current values of environment
 variables, add a new el_set()/el_get() "op" parameter value,
 which can be used to instruct editline which function to use
 for the purpose.   That is EL_GETENV.
 
 This is part of a (long pending, awaiting testing) fix for
 PR bin/58609 - but I'm getting tired of having it sitting uncommitted
 in my source tree - and I think this part is self contained,
 and simple enough, to simply commit.
