[texhax] spurious space with abbrevs.sty

[jtzzaa11-texhax2 at yahoo.com]

Using the abbrevs.sty package for abbrevations, I've defined
\newabbrev{\pc}{personal computer (PC)}[PC]

which expands first to "personal computer (PC)" and afterwards to "PC".

doing something like "{\PC}s" produced "PCs" in my previous texlive installation, but now I've made a fresh installation and I'm getting "PC s", so there's a spurious space.

Any ideas how to fix this?

The abbrevs package on the recent TL installation is from 2001. 


TIA
