[texworks] Why is $PATH ignored?

[Manuel Pégourié-Gonnard]

Hi,

Why does texworks ignore the PATH environment variable? My TeX Live
binaries are in /usr/local/texlive/2008/bin/x86_64-linux, and this
directory is in my PATH, but texworks won't find it until I set it in
the preferences dialog.

I think the directories specified in this dialog should be added to the
regular PATH (preferably with lower priority), not override it.

Manuel.
