[bug#39533] [PATCH] doc: Clarify documentation of guix environment --expose vs.

[Damien Cassou <damien@cassou.me>]

[-- Attachment #1: Type: text/plain, Size: 405 bytes --]

The documentation for --expose and --share parameters are so similar
that the reader has to read both descriptions in parallel to find the
difference.

* doc/guix.texi (Invoking guix environment): Merge the two descriptions
into one, making it much easier to see the difference.
