This is wrong, FWIW. Tilde expansion must happen only at the beginning of
a word or, when in an assignment, at the beginning of the assigned value
or after any unquoted ':'. Note that in `echo foo=~/foo`, what looks like
an assignment is *not* an assignment in POSIX shell lingo because it comes
after the command name.
