This commit begins to bake in a notion of path-style variables.
Prior to this fix, fish would export arrays as ASCII record separator
delimited, except for a whitelist (PATH, CDPATH, MANPATH). This is
surprising and awkward for other programs to deal with, and there's no way
to get similar behavior for other variables like GOPATH or LD_LIBRARY_PATH.
This commit does the following:
1. Exports all arrays as colon delimited strings, instead of RS.
2. Introduces a notion of "path variable." A path variable will be
"colon-delimited" which means it gets colon-separated in quoted expansion,
and automatically splits on colons. In this commit we only do the exporting
part.
Colons are not escaped in exporting; this is deliberate to support uses
like
`set -x PYTHONPATH "/foo:/bar"`
which ought to work (and already do, we don't want to make a compat break
here).
