I wouldn't rely on ~ expansion - not unless you detect that it
has returned empty string.
Although anyone using a system that doesn't support it (most likely
Solaris's /bin/sh) will probably know how to avoid the problem, not
knowing what is wrong is more problematical.
Adding a few 'sh' conditional substitutions to a script might show
some people just how powerful the language is - especially if they
have onely ever seen windows cmd.com .bat scripts.
I've seen some recent systems fail to expand ~ properly (for some
definition of the word 'properly') most noticably cygwin on windoes 7.
