ebuild-env-vars.tex: Clarify that D is not valid in pkg_postinst D in pkg_* phases was first mentioned in SVN r74 (commit f627e46102c6) as a variable specific to the pkg_preinst phase function (replacing IMAGE). pkg_postinst was added in r88 (commit 3da3ee561f1a), but this was reverted in r89 (commit 65c466317718) "D in pkg_postinst == bad". pkg_postinst reappeared when the env vars section was converted to a table in commit 58d3bc0e8301. According to chapter 13 "Merging and Unmerging", the method used to perform the merge is not specified, and merging a regular file or a directory may alter or remove its source under D. Therefore, trying to access any file in D during the postinst phase is an error. The scope of ED follows that of D.
