+ Three main issues accomplished: (1) cleaned up variable names in
+ the filesystem code so that 'pathPtr' is used throughout. (2)
+ applied a round of filesystem optimisation with better handling
+ and caching of relative and absolute paths, requiring fewer
+ conversions. (3) clarifications to the documentation,
+ particularly regarding the acceptable refCounts of objects.
+ Some new tests added. Tcl benchmarks show a significant
+ improvement over 8.4.5, and typically a small improvement over
+ 8.3.5. TCL_FILESYSTEM_VERSION_2 introduced, but for internal
+ use only. There should be no public incompatibilities from
+ these changes. Thanks to dgp for extensive testing.
