This query relates to Bug #66985. Firstly, is it true varexpand() is an attempt
to reinvent shell expansion?
Now, if I have an string such as:
'"asdf" "asdf" "asdf"'
Then varexpand('"asdf" "asdf" "asdf"') results in
'asdf asdf asdf'
Which is broken because the expected result is
'"asdf" "asdf" "asdf"'
Now a work around is to use some quoting:
>>> varexpand('\\"asdf\\" \\"asdf\\" \\"asdf\\"')
'"asdf" "asdf" "asdf"'
This yields the right result, but if I try to use this work around in an
/etc/env.d/ file (as in the bug mentioned above),
--- !empty dir /usr/bin
--- !empty dir /usr
--- !empty dir /etc
>>> original instance of package unmerged safely.
!!! Invalid token (not "=") \\".\\"

Exception: ParseError: Invalid token (not '='): /etc/env.d/50scsh: line 2 in

The contents of the /etc/env.d/50scsh file were:
SCSH_LIB_DIRS=\\"/usr/lib/scsh/modules/0.6\\" \\"/usr/lib/scsh\\" \\".\\"
So varexpand() and its use from env_update() seem to be flawed. How can I work
around this problem?
