- unknown options or missing option values now emit a shorter message
without the entire usage. This makes it easier to identify the errors
and is better aligned with the behaviour of GNU system tools.
====
$ simpleFoam -case
Using: OpenFOAM-plus (see www.OpenFOAM.com)
Build: plus-01234
Error: option '-case' requires an argument
See 'simpleFoam -help' for usage
====
- provide for reduced (-help) and full (-help-full) usage information.
In many cases the reduced usage provided sufficient and easier
to find the information.
- make -srcDoc an alias for -doc-source
- no warnings about option aliases for future dates.
- Can occur with some user names, or mounted paths.
Resolve by using '?' for the separation character.
Since '?' is a shell-glob, it is highly unlikely to occur appear in
filenames. Additionally, it is not a meta-character in standard sed,
nor in the GNU extension (which uses '\?').
The call to foamCleanPath from etc/{bashrc,cshrc} passes all the wildcards
together as a single argument - causing nothing to be cleaned. Now split
the args on whitespace. Also added more IFS hacking to reduce forking.
