Speaking of tilde expansion and bash, are you aware that a POSIX
interpretation was just issued for review that states that the result of
tilde expansion should behave as though it were quoted, and not undergo
further pathname expansion or field splitting?  The interpretation
(Austin-202) is still undergoing review, so it requires a login to read:
https://www.opengroup.org/austin/interps/protected/uploads/20/15352/AI-202.txt

But anyone can read the original report that spawned the interpretation
http://www.opengroup.org/austin/aardvark/latest/xcubug2.txt (search for
number 169)

The reasoning behind this is that ~ already represents a single path name,
so it should not be further expanded.  However, bash 3.2 does not obey
this rule (it avoids field splitting, but mistakenly performs pathname
expansion if $HOME contains glob characters).
