Hm, this is supposed to already work in teTeX-3.0 and TeXlive 2005. However, the texmf.cnf files in both do not use the tilde, but $HOME. If I do export HOME=/home/frank/ then kpsewhich --expand-var='$TEXMFHOME' takes ages and scans the complete home dir; if I replace "$HOME" by "~" in texmf.cnf, it is fast again. However, a kpsewhich search for a file still takes long and looks everywhere (hash_lookup) below $HOME. All in all, it seems as if - tilde expansion is never used in the standard setup, and - removal of double slashes only works partially. These tests were done with teTeX 3.0 (Web2C 7.5.4).
