- handle sourcing bashrc with a relative path (issue #383)
- handle sourcing from bash and zsh.
Still need manual intervention when sourcing dash, sh, or ksh.
- replace grep in etc/cshrc with sed only
- logical instead of physical path for WM_PROJECT_DIR (issue #431).
Doesn't seem to be possible for csh/tcsh.
* Continue using physical locations when comparing directories,
but not for the top-level FOAM_INST_DIR, WM_PROJECT_DIR.
- relocate WM_CC, WM_CXX overrides from etc/config.*/compiler
to etc/config.*/settings to ensure that they are left untouched
when etc/config.sh/compiler is sourced while making third-party
packages (eg, gcc, llvm, CGAL).
- provide fallback FOAM_TUTORIALS setting in RunFunctions
STYLE: remove "~OpenFOAM" fallback as being too rare, non-obvious
